Description
A new class of ferromagnets-dilute magnetic semiconductors (DMS) based on III-V materials (e.g. In1-xMnxAs or Ga1-xMnxAs)-which are both semiconducting and ferromagnetic (FM) at low temperature, have attracted a great deal of attention (as working media for spintronics) following the discovery of ferromagnetism in Ga1-xMnxAs. However, practical spintronics applications of these DMS are severely limited by the fact that they are FM only at low temperature (below about 150K). Here we present the results of our studies in III-V (InSb) and II-IV-V2 (CdGeAs2 and CdGeP2) materials doped with Mn which exhibit robust ferromagnetism at room temperature. μSR experiments show that this ferromagnetism is a bulk phenomenon
