摘要：

Jaccarino and Walker proposed that in certain alloy systems a considered kind of atom attains a constant value of the magnetic moment if it is surrounded by at least a minimum number of nearest-neighbor atoms of a certain kind, and that it is nonmagnetic otherwise. It is shown by ab initio supercell calculations within the LMTO method that the system Nb1-xMox with 1% iron approximately fulfills the Jaccarino-Walker hypothesis, whereas the alloy FexRh1-x does not. The physical mechanism for the destruction of the Fe moment in bcc alloys with 4d and 5d transition metals is elucidated.
