Abstract

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 nh=3×10 17cm-3 at 350 K. The measured magnetic moment per Cr was 0.83μB at 5 K.
