Exchange Interaction

Chapter
Part of the Springer Series in Materials Science book series (SSMATERIALS, volume 158)

Abstract

As was shown in Sect. 3.4, spontaneous magnetization arises through exchange interactions. There are different detailed mechanisms of exchange interaction in solids. Classic expression of exchange energy is in common use in magnetism. This chapter introduces main theoretical models of the mechanisms and the classic expression, and contains the sections of Direct exchange interaction in solid; Superexchange interaction; RKKY exchange interaction; Double exchange interaction; and classic expression of exchange energy.
