摘要
The band structure of FeSi has been studied by the ab initio full-potential LMTO-PW including the applied field explicitly. From these calculation, the first-order metamagnetic transition to the metallic magnetic state at the critical magnetic field of about B-cr = 170 T has been found. A large step-like magnetization induces a magnetic moment of 0.7 mu(B)/cell. The hysteresis effect, which was found for the first time, is also discussed. (C) 1998 Elsevier Science B.V.
