Abstract

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 Néel 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.
