Summary
In this chapter, we studied magnetic ordering and spin wave excitations of magnetic solids. We first reviewed Heisenberg exchange interactions of atoms and then discussed spontaneous magnetization and domain wall properties of ferromagnets. The zero-temperature properties of Heisenberg ferromagnets and antiferromagnets are described. Spin wave excitations and magnon heat capacities of ferromagnets and antiferromagnets are also discussed. Finally, Stoner model is introduced as an illustration of itinerant ferromagnetism.
