Ferromagnetism, Antiferromagnetism, and Ferrimagnetism. 229 Downloads; Abstract. C. D. Graham. “My work of 1948 predicted the existence of substances of which the spontaneous attraction presents very unusual abnormal thermal varia-tions. The present paper is a sequel to the paper by Karchev (2008 J. In physics, a ferrimagnetic material is one that has populations of atoms with opposing magnetic moments, as in antiferromagnetism; however, in ferrimagnetic materials, the opposing moments are unequal and a spontaneous magnetization remains. Ferromagnetism is a physical phenomenon. A property exhibited by certain metals, alloys, and compounds of the transition (iron group), rare-earth, and actinide elements in which, below a certain temperature called the Curie temperature, the atomic magnetic moments tend to line up in a common direction.

Magnetic Dipoles. Exchange interactions 3. a form of antiferromagnetism . Ferrimagnetism is a term that was originally proposed by Néel to describe the magnetic ordering phenomena in ferrites (see Transition Metal Oxides: Magnetism), in which Fe ions appear in two different ionic states and hence bear different magnetic moments with mutual antiferromagnetic coupling. The ferrimagnetism originates from the ferromagnetically aligned spins within the c -plane coupled antiferromagnetically between adjacent planes with ordered iron vacancies. Band magnetism 4.
