ferrimagnetism

Néel pointed out (1947) that materials could also exist showing ferrimagnetism.

This is, like ferromagnetism and ferrimagnetism, a manifestation of ordered magnetism.

This gives rise to ferromagnetism, antiferromagnetism or ferrimagnetism.

Antiferromagnetism, ferrimagnetism, and ferromagnetism are cooperative phenomena of the magnetic spins within a solid.

They give rise to ferromagnetism, antiferromagnetism or ferrimagnetism, depending on the nature and relative orientations of the individual spins.

Net moment via antiferromagnetic coupling of non-equal spin centers (ferrimagnetism)

Replies: There are many different types of magnetic behavior - ferromagnetism, ferrimagnetism, antiferromagnetism, diamagnetism, paramagnetism.

On the other hand, the definition of multiferroics can be expanded as to include non-primary order parameters, such as antiferromagnetism or ferrimagnetism.

Pyrrhotite, FeS, a mineral, which displays ferrimagnetism and crystallizes in monoclinic system.

The exchange interaction is also responsible for the other types of spontaneous ordering of atomic magnetic moments occurring in magnetic solids, antiferromagnetism and ferrimagnetism.

Exchange interaction can occur in clusters and infinite lattices, resulting in ferromagnetism, antiferromagnetism or ferrimagnetism depending on the relative orientations of the individual spins.

The first discovered magnetic substance, magnetite, is a ferrite and was originally believed to be a ferromagnet; Louis Néel disproved this, however, after discovering ferrimagnetism.

The past magnetic field is recorded mostly by iron oxides, such as magnetite, that have some form of ferrimagnetism or other magnetic ordering that allows the Earth's field to magnetize them.

Ferromagnetism (including ferrimagnetism) is the strongest type; it is the only type that creates forces strong enough to be felt, and is responsible for the common phenomena of magnetism encountered in everyday life.

The oldest known magnetic substance, magnetite (iron(II,III) oxide; FeO), is a ferrimagnet; it was originally classified as a ferromagnet before Néel's discovery of ferrimagnetism and antiferromagnetism in 1948.

More recently, however, different classes of spontaneous magnetization have been identified when there is more than one magnetic ion per primitive cell of the material, leading to a stricter definition of "ferromagnetism" that is often used to distinguish it from ferrimagnetism.

The ferrimagnetism of FeO arises because the electron spins of the Fe and Fe ions in the octahedral sites are coupled and the spins of the Fe ions in the tetrahedral sites are coupled but anti-parallel to the former.
