Known ferrimagnetic materials include yttrium iron garnet (YIG); cubic ferrites composed of iron oxides with other elements such as aluminum, cobalt, nickel, manganese, and zinc; and hexagonal ferrites such as PbFe12O19 and BaFe12O19 and pyrrhotite, Fe1−xS.
Ferrimagnetism is the magnetism of the oxides of the ferromagnetic elements. These are variously called ferrites and garnets. The basic ferrite is magnetite (Fe3O4) which can be written as FeO · Fe2O3.
Ferrimagnetic materials contain magnetic moments aligned antiparallel to one another, as illustrated in the figure below, similar to antiferromagnetic materials. … Using manganese oxide, MnO, as an example, in its crystal oxygen ions, O2-, sit between manganese ions, Mn2+, as shown schematically in the figure below.
Fe3O4 is ferrimagnetic at room temperature because in its crystals magnetic numbers of Fe (II) and Fe (III) ions are unequal in magnitude and aligned in antiparallel direction. But when heated at 850 K the arrangement randomized and substance becomes paramagnetic.
Antiferromagnetic materials
Examples include hematite, metals such as chromium, alloys such as iron manganese (FeMn), and oxides such as nickel oxide (NiO). There are also numerous examples among high nuclearity metal clusters.

 Diamagnetic substances are weakly repelled by a magnetic field for example, H2O, NaCl and C6H6.  Ferromagnetic substances are strongly attracted by the magnetic field and show magnetism even when the magnetic field is removed. For example, iron, cobalt, nickel.
Superparamagnetism is a property occurring principally in small, single-domain magnetic particles without magnetic memory. … Unlike ferromagnetic materials, therefore, superparamagnetic substances do not retain any net magnetization once the external field has been removed. In other words, they have no magnetic memory.
Ferromagnetism is a kind of magnetism that is associated with iron, cobalt, nickel, and some alloys or compounds containing one or more of these elements. … Below the Curie point, atoms that behave as tiny magnets in ferromagnetic materials spontaneously align themselves.
Only certain materials, such as iron, cobalt, nickel, and gadolinium, exhibit strong magnetic effects. These materials are called ferromagnetic. Ferromagnetic materials will respond strongly to magnets and can also be magnetized themselves.
Some magnetic domains in a ferrimagnetic material point in the same direction and some in the opposite direction. However, in ferromagnetism they all point in the same direction.
The magnetic interaction among iron ions at octahedral and tetrahedral sites is antiferromagnetic and that among octahedral ions is ferromagnetic; overall a ferrimagnetic arrangement of Fe3O4. Therefore, the net magnetic moment in Fe3O4 is due to Fe2+ ions (4 μB).
The re are no unpaired electrons in sodium chloride and sodium chloride is diamagnetic. Manganese(II) sulfate monohydrate is strongly attracted by the magnet, which shows that it is paramagnetic.

In particular, CrO2 attracts special interest since it is the only half-metallic (HM) ferromagnetic (FM) material in 3d transition metal dioxides.
Antiferromagnetism, type of magnetism in solids such as manganese oxide (MnO) in which adjacent ions that behave as tiny magnets (in this case manganese ions, Mn2+) spontaneously align themselves at relatively low temperatures into opposite, or antiparallel, arrangements throughout the material so that it exhibits …
Bulk ZnFe2O4 exhibiting normal spinel structure is a weak antiferromagnet with a Neél-temperature of 10.5 K [21], while epitaxial ZnFe2O4 thin films exhibit a higher Néel temperature of 43 K [22].
