摘要：

We have fabricated Cr and Fe-doped bulk Ge single crystal using the vertical gradient solidification method. The Cr-doped Ge single crystal showed ferromagnetic ordering at 126 K, as determined from temperature dependent magnetization and resistance measurements. The measured magnetic moment per Cr was 0.83 mu(B) at 5 K. On the other hand, Fe0.05Ge0.95 showed ferromagnetic ordering at 233 K. The coersive field was 80 Oe at 5 K.
