ferrimagnetism

(ˌfɛrɪˈmæɡnɪˌtɪzəm)
n
(General Physics) a phenomenon exhibited by certain substances, such as ferrites, in which the magnetic moments of neighbouring ions are antiparallel and unequal in magnitude. The substances behave like ferromagnetic materials. See also antiferromagnetism
ferrimagnetic adj
ThesaurusAntonymsRelated WordsSynonymsLegend:
Noun1.ferrimagnetism - a phenomenon in ferrites where there can be incomplete cancellation of antiferromagnetic arranged spins giving a net magnetic moment
antiferromagnetism - magnetic field creates parallel but opposing spins; varies with temperature

NiFe2O4 has an inverse spinel structure showing ferrimagnetism due to the magnetic moment of the anti-parallel spins between the Fe+3 ions in tetrahedral region and the Ni+2 ions in the octahedral region [17].
For example, the phenomenological theory of ferrimagnetism of bulk materials remains still based on the Neel classification according to the temperature dependence of saturation magnetization and describes seven main types of such dependence at once [27].
Ferrimagnetism is similar to ferromagnetism (e.g., spontaneous magnetization, Curie temperatures, and magnetic hysteresis), but this biocompatible family is based on superparamagnetic iron oxide nanoparticles (SPIO-NPs) and occurs in magnetite ([Fe.sub.3][O.sub.4]) or its oxidized form, maghemite ([gamma]- [Fe.sub.3][O.sub.4]).
