Curie temperature — In physics and materials science, the Curie temperature (Tc), or Curie point, is the temperature at which a ferromagnetic or a ferrimagnetic material becomes paramagnetic on heating; the effect is reversible. A magnet will lose its magnetism if… … Wikipedia
Curie's law — In a paramagnetic material the magnetization of the material is (approximately) directly proportional to an applied magnetic field. However, if the material is heated, this proportionality is reduced: for a fixed value of the field, the… … Wikipedia
Curie point — The Curie point (Tc), or Curie temperature, is a term in physics and materials science, named after Pierre Curie (1859 1906), and refers to a characteristic property of a ferromagnetic or piezoelectric material. Curie point in ferromagnetic… … Wikipedia
Curie–Weiss law — The Curie Weiss law describes the magnetic susceptibility χ of a ferromagnet in the paramagnetic region above the Curie point: where C is a material specific Curie constant, T is absolute temperature, measured in kelvins, and Tc is the Curie… … Wikipedia
Curie-Weiss law — The Curie Weiss law describes the magnetic susceptibility of a ferromagnet in the paramagnetic region above the Curie point::chi = frac{C}{T T {cwhere:chi is the magnetic susceptibility: C is a material specific Curie constant: T is absolute… … Wikipedia
magnetism — /mag ni tiz euhm/, n. 1. the properties of attraction possessed by magnets; the molecular properties common to magnets. 2. the agency producing magnetic phenomena. 3. the science dealing with magnetic phenomena. 4. strong attractive power or… … Universalium
Paramagnetism — is a form of magnetism which occurs only in the presence of an externally applied magnetic field. Paramagnetic materials are attracted to magnetic fields, hence have a relative magnetic permeability greater than one (or, equivalently, a positive… … Wikipedia
rock — rock1 rockless, adj. rocklike, adj. /rok/, n. 1. a large mass of stone forming a hill, cliff, promontory, or the like. 2. Geol. a. mineral matter of variable composition, consolidated or unconsolidated, assembled in masses or considerable… … Universalium
Rock — /rok/, n. a male given name. * * * I In geology, a naturally occurring and coherent aggregate of minerals. The three major classes of rock igneous, sedimentary, and metamorphic are based on the processes that formed them. These three classes are… … Universalium
Magnetochemistry — is concerned with the magnetic properties of chemical compounds. Magnetic properties arise from the spin and orbital angular momentum of the electrons contained in a compound. Compounds are diamagnetic when they contain no unpaired electrons.… … Wikipedia
