摘要：

Magnetic structures of three compounds with the crystal structure of ThCr2Si2 type: CeMn2Ge2, HoMn2Si2 and HoMn2Ge2 were determined by neutron diffraction using polycrystalline samples. In CeMn2Ge2 no magnetic moment on the Ce ion could be detected but Mn moments show ferromagnetic order. Antiferromagnetic ordering in the form of a flat spiral of Ho moments was found in HoMn2Si2 and HoMn2Ge2, stable up to the respective Néel points at (13±2) K and (7±2) K. The Mn magnetic sublattice shows collinear antiferromagnetism with +-+- sequence. © 1990.
