Abstract
Magnetic and magneto-optical properties were measured at room temperature in the Mn-diffused surface layer of a CdGeP2 single crystal. The magnetization curve measured using VSM clearly shows a ferromagnetic hysteresis loop with Hc=0.4 kOe superposed on the diamagnetic component. The ferromagnetic Curie temperature was determined as 320 K from the magnetization vs. temperature curve. The magneto-optical Kerr effect was measured between 1.2 and 4 eV. The peak Kerr ellipticity of 0.14 deg appeared around 1.75 eV.Keywords
