摘要：
Neutron-diffraction measurements were made on an ordered Mn3Ir single crystal in a wide temperature range up to 1030 K. The ordered Mn3Ir alloy was found to maintain an antiferromagnetic (AF) triangular spin structure up to the Neel temperature T-N=960 +/- 10 K. The lattice parameter a shows a continuous change in the temperature range including T-N. In contrast to the isostructural ordered Mn3Pt alloy, these observations indicate that an AF-AF phase transition is absent in the ordered Mn3Ir alloy. (C) 1999 American Institute of Physics.
