The spinel ferrites are the most readily recognizable ferrites. The most familiar member of this group, magnetite (Fe 3 O 4), is not only the archetypal ferrite but indeed the earliest material recognized to be magnetic, giving birth to the term "magnetism" itself.. Spinel ferrites can be described by the formula MFe 2 O 4, where M is usually a divalent …
