ferromagnetic materials
121Colossal 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… …
122Geometrically frustrated magnet — Geometrical frustration and ice rules The word frustration was introduced to describe the situation where a system cannot simultaneously minimize the interaction energies between its components [cite journal last = Schiffer first = P. authorlink …
123GaMnAs — Gallium manganese arsenide (abbreviated GaMnAs, or (Ga,Mn)As, or Ga1 xMnxAs) is a dilute III V magnetic semiconductor based on doping gallium arsenide (GaAs) with manganese (Mn). Manganese atoms are substituted for gallium, creating both a local… …
124amorphous solid — ▪ physics Introduction any noncrystalline solid in which the atoms and molecules are not organized in a definite lattice pattern. Such solids include glass, plastic, and gel. Solids and liquids (liquid) are both forms of condensed… …
125Domain theory of ferromagnetism — explains[1] two significant observations of materials such as iron: The material may become strongly magnetized by application of a weak external magnetizing field. The same specimen may return to the demagnetized state when the external field is …
126Antiferromagnetism — In materials that exhibit antiferromagnetism, the magnetic moments of atoms or molecules, usuallyrelated to the spins of electrons, align in a regular pattern with neighboring spins (on different sublattices) pointing in opposite directions. This …
