ferromagnetic phase transition
21Ferroics — is the generic name given to the study of ferromagnets, ferroelectrics, and ferroelastics. Essentially the basis of this study is to understand the large changes in physical characteristics that occur in a very short temperature range. The… …
22Renormalization group — In theoretical physics, the renormalization group (RG) refers to a mathematical apparatus that allows systematic investigation of the changes of a physical system as viewed at different distance scales. In particle physics, it reflects the… …

24Metamagnetism — is a blanket term used loosely in physics to describe a sudden (often, dramatic) increase in the magnetization of a material with a small change in an externally applied magnetic field. The metamagnetic behavior may have quite different physical… …
25Curie 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… …
26Order and disorder (physics) — In physics, the terms order and disorder designate the presence or absence of some symmetry or correlation in a many particle system. In condensed matter physics, systems typically are ordered at low temperatures; upon heating, they undergo one… …
27Colossal magnetoresistance — (CMR) is a property of some materials, mostly manganese based perovskite oxides, that enables them to dramatically change their electrical resistance in the presence of a magnetic field. The magnetoresistance of conventional materials enables… …
28Dielectric — A dielectric is an electrical insulator that can be polarized by an applied electric field. When a dielectric is placed in an electric field, electric charges do not flow through the material, as in a conductor, but only slightly shift from their …
29QCD vacuum — The QCD vacuum is the vacuum state of quantum chromodynamics (QCD). It is an example of a non perturbative vacuum state, characterized by many non vanishing condensates such as the gluon condensate or the quark condensate. These condensates… …
30Magnetic refrigeration — Gadolinium alloy heats up inside the magnetic field and loses thermal energy to the environment, so it exits the field cooler than when it entered. Magnetic refrigeration is a cooling technology based on the magnetocaloric effect. This technique… …
