Summary

The basic features and the various categories of magnetic materials are presented. Concepts such as magnetic domains, saturation magnetization, Bloch walls, hysteresis, soft and hard magnetic materials, remanance, and coercivity are introduced. The temperature dependence of the saturation magnetization and the magnetic susceptibility for simple ferromagnets, ferrimagnets, and antiferromagnets and the corresponding universal critical exponents are presented. Representative materials of each category of magnetic solids are mentioned and their properties are summarized. Thermodynamics provide an explanation for the temperature dependence of the saturation magnetization and the susceptibility, for the thickness of the Bloch walls, etc. Finally, the topic of spintronics is summarized, by briefly reviewing the efforts to exploit the electronic spin degrees of freedom at the time of this writing.
