摘要：

Electronic structures of new Heusler alloys Ru(2)MnZ (Z = Si, Ge, Sn and Sb) were calculated to examine the magnetic properties. In this paper, it will be shown that an antiferromagnetic state is stable for these alloys, where the Mn magnetic moments are aligned ferromagnetically in the (111) plane and antiparallel along the [111] direction. It will also be shown that the alloys Ru(2)MnZ (Z = Si, Sb) can be half-metallic in a ferromagnetic phase.
