We report molecular beam epitaxy of a ferromagnetic semiconductor (Ga,Mn)Sb, which is a single crystal without detectable second phases. We report also the details of magnetotransport properties of (Ga,Mn) Sb and the effects of electric fields on them. The difference between the properties observed here and properties of those reported earlier for a ferromagnetic semiconductor (Ga,Mn)As, provides information critical for further understanding of fundamental and device physics of ferromagnetic semiconductors.
