在本章中，我们将把注意力集中在铁氧体和其他一些密切相关的材料上。对铁氧体的极大兴趣源于其自发磁化和高电阻率的独特组合。所观察到的磁化强度的结果从两个非等效的磁性离子在晶体结构中的子晶格的磁化强度的差异。这种类型的材料应严格指定为“亚铁磁性”，在某些方面与反铁磁性物质的关系比与铁磁性物质的关系更密切，铁磁性物质的磁化强度来自所有磁矩的平行排列。我们将不坚持这种特殊的命名法，除非强调效果，这是由于子格的存在。
In this chapter, we will restrict our attention to the ferrites and a few other closely related materials. The great interest in ferrites stems from their unique combination of a spontaneous magnetization and a high electrical resistivity. The observed magnetization results from the difference in the magnetizations of two non-equivalent sub-lattices of the magnetic ions in the crystal structure. Materials of this type should strictly be designated as “ferrimagnetic” and in some respects are more closely related to anti-ferromagnetic substances than they are to ferromagnetics in which the magnetization results from the parallel alignment of all the magnetic moments present. We shall not adhere to this special nomenclature except to emphasize effects, which are due to the existence of the sub-lattices.
