Two materials found in nature, lodestone (or magnetite, an oxide of iron, Fe 3 O 4) and iron, have the ability to acquire such attractive powers, and they are often called natural ferromagnets. Some features of the site may not work correctly. Ferrimagnetism is therefore similar to ferromagnetism.

FERROMAGNETIC MATERIALS Those substances, which when placed in magnetic field are strongly magnetised in the direction of the magnetising field. FERRIMAGNETISM Close Fig. From this viewpoint, ferromagnetism is a particular case of ferrimagnetism in which a substance contains only one sublattice, and antiferromagnetism is a particular case in which all sublattices consist of identical magnetic ions and J = 0. Ferromagnetic Materials. The Néel theory of ferrimagnetism is a molecular-field theory of magnetic ordering in systems which contain nonequivalent substructures of magnetic ions. However, ferro- and ferrimagnets have very different magnetic ordering. Ferrimagnetism occurs chiefly in magnetic oxides known as ferrites.The natural magnetism exhibited by lodestones, recorded as early as the 6th century bc, is that of a ferrite, the mineral magnetite, a compound containing negative oxygen ions O 2-and positive iron ions in two states, iron(II) ions, Fe 2 +, and iron(III) ions, Fe 3 +.The oxygen ions are not magnetic, but both iron ions are. Ferromagnetism, Antiferromagnetism, and Ferrimagnetism. 2(e)).

FERRIMAGNETISM Close Fig. The other three are diamagnetism, paramagnetism, and ferrimagnetism. More specifically the magnetism and magnetization of a solid will depend on the movement of electrons in an atom.It can thus be said that each electron of an atom behaves like a magnet, lending the whole solid its magnetic property. These ceramics are called ferrites, and the effect is known as Ferromagnetism. You are currently offline. Authors; Authors and affiliations; Gerald F. Dionne; Chapter. Uploaded by.

The unit cell of the spinel lattice. 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. Both compounds are ferrimagnetic with Curie temperatures of 450 and 314 K for Fe 7 Se 8 and Fe 3 Se 4, respectively (Hirakawa, 1957; Okazaki and Hirakawa, 1956).

The difference between ferromagnetism and ferrimagnetism is that the Curie temperature of ferromagnetic materials is higher than that of ferrimagnetic materials. Anisotropy The ferrimagnetism originates from the ferromagnetically aligned spins within the c -plane coupled antiferromagnetically between adjacent planes with ordered iron vacancies. It is possible in a simple lecture demonstration to synthesize Fe3O4 right before student's eyes and to show its interaction with a magnetic field, comparing it to a paramagnetic material. Nathan King. • In a magnetic field, the dipoles of a cation may line up with the field, while dipoles of other cation may not. This gives rise to the possibility of a ‘ compensation point ’, a temperature T, at which Materials can be divided into several groups based on their magnetic properties.
