01.03.2009 · Iron oxides exist in many forms in nature, with magnetite (Fe 3 O 4), maghemite (γ-Fe 2 O 3), and hematite (α-Fe 2 O 3) being probably the most common. These three oxides are also very important technologically, and they are therefore the subject of this review. Some of their physical and magnetic properties are summarized in Table 1.

Ferrite | iron oxide compound | Britannica

Ferrite, a ceramic-like material with magnetic properties that are useful in many types of electronic devices. Ferrites are hard, brittle, iron-containing, and generally gray or black and are polycrystalline— i.e., made up of a large number of small crystals. They are composed of iron oxide and one or more other metals in chemical combination.

Ferromagnetism is the basic mechanism by which certain materials (such as iron) form permanent magnets. This means the compound shows permanent magnetic properties rather than exhibiting them only in the presence of an external magnetic field (Figure (PageIndex{1})). In a ferromagnetic element, electrons of atoms are grouped into domains in which each domain has the same charge. In the ...

16.11.2018 · The defining properties of magnets are that they attract some materials and the opposite poles of other magnets, and repel like poles of other magnets. So if you have two permanent bar magnets, pushing two north (or south) poles together produces a repulsive force, which gets stronger the closer the two ends are brought together.
