摘要
Ferromagnetic behaviour above room temperature has been observed in Mn-ions implanted Si0.75Ge0.25. The 900 degrees C annealed sample with Mn dosage of 2x10(16) cm(-2) exhibit saturation magnetization, saturation field and coercive field of similar to 9 emu/cm(3) and similar to 1500 Oe and similar to 60 Oe respectively at 300K.
