摘要：

We have fabricated Cr-doped bulk Ge single crystal using the vertical gradient solidification method. The material shows ferromagnetic ordering at 126 K, as determined from temperature-dependent magnetization and resistance measurements. A sample with x=0.01 was p type with n(h)=3x10(17) cm(-3) at 350 K. The measured magnetic moment per Cr was 0.83mu(B) at 5 K. (C) 2002 American Institute of Physics.
