Magnetic semiconductors are of interest because they reveal unique physics that is a result of interaction between magnetism and semiconducting properties, and provide opportunities to observe new phenomena and to demonstrate new schemes of device operation based on them. Their fascinating properties have played a leading role in developing a research field of semiconductor spintronics. Device concepts proposed and demonstrated through magnetic semiconductor research have now extended over metal spintronics. To observe spin-related cooperative phenomena in semiconductors, one needs to introduce a sizable amount of magnetic impurities to the host semiconductor, which often exceeds the solubility limit. Such a magnetic semiconductor does not exist in nature and is metastable. Crystal growth plays a decisive role in preparing metastable semiconductors. In this chapter, we review the syntheses of magnetic semiconductors and their basic properties and its relation to growth parameters.
