The purpose of this site is to provide a forum for and challenges to a unique concept of the universe. You will be presented theories and concepts that are consistent, invariable and logical and for the most part easy for a junior high school student to understand. Though the concepts will appear controversial it is my intention to follow the conclusions of early developments in science and the logic of one basic rule which has been largely ignored. The result is that much of what has been taught in high school and university will be challenged. realscnc bookmarks Basic Forces - Attraction / repulsion; Expansion of a gas; Inertia of nucleus provides stable anchor; Explanation of so called waves; Explanation of magnetism,- repulsion only; Explanation of radiant energy; What it is; How it is created.

home français Semiconductors and magnetism (Physics of semiconductors) Topics Incorporating magnetic properties into semiconductor heterostructures would allow one to manipulate not only the charge of the carriers (electrons in the conduction band, holes in the valence band) as in usual microelectronics, but also their spin. This is of interest in order to achieve semiconductor spintronics; it could even be a way towards quantum computing... But keep your old computer for a while, first we have to understand how this could be realized in a sample... In our lab, we try to do that: in diluted magnetic semiconductors , i.e., usual semiconductors in which we add magnetic impurities (Mn) and free carriers to induce a ferromagnetic interaction between the Mn spins: hence ferromagnetism in inside; in hybrid structures , i.e., structures with a ferromagnetic metal is grown on top of the semiconductor. In both cases, samples are grown by molecular beam epitaxy, within the Joint CEA-CNRS-UJF Group "Nanophysique et semi-conducteurs". 1. Diluted magnetic semiconductors

KHWARZIMIC SCIENCE SOCIETY M agnetism Through the Ages Jawad Aslam Magnetism Home WHAT IS MAGNETISM? Magnetism is a phenomenon associated with the motion of charges. It involves magnetic fields, which are regions wherein a force is exerted on a current carrying medium, and the effects of such fields. All materials have some magnetic properties. The magnetic properties of matter largely depend upon how the electrons orbiting the nuclei of atoms behave. Diamagnetism is a weak effect common to all substances and results from the orbital motion of electrons. In certain substances this is marked by a stronger effect, paramagnetism, due to electron spin. Some materials such as iron also display ferromagnetism. MAGNETISM: A historical survey The magnetic phenomenon has been known since antiquity. The ancient Greek knew about the magnetic force of both magnetite and rubbed amber. Magnetite, a magnetic oxide of iron mentioned in Greek texts as early as 800 BC, was mined in the province of Magnesia in Thessaly. Thales of Miletus is considered to have been the first man to study magnetic forces. According to Lucretius, a Roman philosopher in the first century BC, the term magnet was derived from the province of Magnesia. Pliny the Elder, however attributes it to the supposed discoverer of the material, the shepherd Magnes whose shoes and the tip of whose staff stuck fast in a magnetic field while he pastured his "the nails of flocks."

87. Materials By Design: Magnetic Properties Of Materials Types of magnetism. Temperature, stress and impurities can all affect magnetic propertiesand play an important role in using these materials for engineering http://www.mse.cornell.edu/courses/engri111/magnet2.htm

Types of Magnetism Paramagnetism If the magnetic moments of the atoms are random, we say that the material is paramagnetic . The magnetic moments from atoms do not interact with each other at all. If an external magnetic field is applied, the magnetic moments are free to align with the field. Ferromagnetism If the moments interact to cause each other to align in the same direction, they are called ferromagnetic . Iron, cobalt and nickel are ferromagnets, as are the magnets on your refrigerator. Antiferromagnetism If the moments interact to cause an alternating pattern such as in manganese, the material is said to be antiferromagnetic Ferrimagnetism Some materials have different types of atoms with different moments, which interact. For example, Fe O has both Fe and Fe atoms with correspondingly different moments, which are located at different sites within the structure. These cause ferrimagnetic behavior, because some of the moments are canceled by other atoms, but some are not. Temperature, stress and impurities can all affect magnetic properties and play an important role in using these materials for engineering applications.

Printer-friendly version Explaining and Applying Magnetism Principle of Operation: Hard phase stiffens response of soft high-magnetization phase in magnetic nanocomposite structures. Scientific Impact: These studies have advanced the science of magnetic materials and paved the way for manufacture of magnet structures with greater mechanical strength and stability. Researchers benefit from these materials through their use in permanent magnet devices at Office of Science-supported synchrotrons and most other light sources around the world. Social Impact: Magnetic materials are used in many industrial and consumer devices such as motors, generators, and computers. Improvements in magnet properties and processing characteristics will enhance energy efficiency; for example, the use of rare earth magnets in more efficient electric motors could save the nation several billion dollars annually.

Magnetism and Magnetic Materials at the School of Physics and Astronomy, University of St Andrews Bob Cywinski, Sue Kilcoyne, Steve Lee, Peter Riedi 5 Research Fellows, 4 Research Students Preparation of metallic alloys The fundamental magnetic properties of elements, alloys and compounds are studied by the Magnetism and Superconductivity Group. In particular we are addressing problems which are central to modern magnetism, namely the interplay of structural, electronic and magnetic properties, the mechanisms responsible for magnetic moment formation in elements and alloys and the interactions which lead to often complex magnetic structures, magnetic relaxation and spin glass behaviour. Principal contacts: Bob Cywinski, Steve Lee, Peter Riedi Nanostructured magnetic materials are a focus of considerable current scientific and technological interest. Firstly they provide model systems in which fundamental physical phenomena such as quantum tunnelling and surface magnetism can be probed, and secondly the control of particle size, morphology and magnetic anisotropy can lead to enhanced functionality and the optimisation of technologically important properties such as giant magneto-resistance (GMR). We are interested in nanostructured materials prepared by metallurgical and chemical routes (for example multilayer systems and fine grain metallic particles), and also those of biological origin (such as iron storage proteins and limpets' teeth).

Next: Waves vs. particles Up: Electricity and magnetism Previous: Electricity Magnetism The earliest observations on magnets can also be traced back to the early Greeks (eg. Thales of Miletus; see Sect. ). The Chinese literature also has extensive references to naturally occurring magnets (then called loadstones). The fact that magnets align in a unique way, together with the fact that the Earth itself is a magnet, lead to the discovery of the compass. This was of paramount importance to the development of civilization. The earliest known compass appeared in China by the first century A.D.; it arrived in Europe by the twelfth century A.D. According to thirteenth-century philosophy, the compass needle points towards the North star which, unlike all other stars, in the night sky, appears to be fixed. Thus, philosophers reasoned that the lodestone obtained its ``virtue'' from this star. Better observations, however, showed that the needle does not point exactly to the North Star and eventually it was shown that it is the Earth that affects the compass. Apart from the roundness of the Earth, magnetism was the first property to be attributed to the body of the Earth as a whole: Magnus magnes ipse est globus terrestris [the whole Earth is a magnet].

Non-Vertebrate Paleontology Laboratory Mechanical properties Chemical properties Optical properties The Science of Minerals ... Home Electrical and Magnetic Properties Electricity and magnetism are two expressions of a single force, called "electromagnetism". Two electrical properties that have important industrial and electronic applications are piezoelectricity and pyroelectricity , although these properties are not typically used in mineral identification. These properties are shown by certain classes of minerals or synthetic crystalline materials that lack a center of symmetry. Magnetism is an important diagnostic tool for a few minerals. Radioactivity , or the spontaneous decay or disintegration of an unstable atomic nucleus accompanied by the emission of electromagnetic energy, can be detected in some minerals with a Geiger counter and for these minerals, it is a diagnostic property. Piezoelectricity is the ability of a mineral or crystal to acquire opposing electrical charges on opposing surfaces when mechanical stress (such as bending, stretching, or compression) is applied to the crystal. The piezoelectric effect is caused by the displacement of ionic charges within a crystal structure, and the magnitude of the charge generally is proportional to the amount of stress applied. Removal of the stress reverses the effect. This electrical charge can be converted into a voltage using a charge amplifier. Of the minerals in the twenty crystal classes that lack a center of symmetry, only a few are piezoelectric to any significant degree. Piezoelectricity was first discovered in quartz crystals. This effect allows them to be used in certain sorts of radio tuners (first done in 1921, but now largely replaced by other types), in the timing mechanisms of quartz watches, and in the electronics industry. Tourmaline, another strongly piezoelectric mineral, is used in gauges to measure transient blast pressures.
