Abstract
Materials and properties of two types of semiconductors with spontaneous magnetization or ferromagnetic and paramagnetic properties are explained: Compound materials and diluted magnetic semiconductors. A short introduction to semiconductor spintronics covers the concepts of spin transistor and spin LED.

Notes
- 1.
Such superexchange leads to antiferromagnetic interaction if the bond angle is ‘close’ to 180\(^{\circ }\).
- 2.
This model is also called the Zener model.
- 3.
MnAs is a ferromagnetic metal. MnAs clusters can be a problem since they create ferromagnetic properties but not in the way the DMS is supposed to work.
- 4.
This use of the term ‘anomalous’ should be distinguished from the historical use of ‘anomalous’ Hall effect for the sign reversal of the Hall voltage for hole conductors.
