中文摘要The site preference of Mn atoms in Heusler alloy Mn2NiSb can be influenced obviously by different preparing methods. Mn atoms enter the A and B sites after arc-melting and subsequent annealing, and form an Hg2CuTi-type of structure. However, after melt-spinning, the Mn atoms tend to occupy the (A, C) sites and form the Cu2MnAl-type of structure. The electronic structure calculations suggest that the Hg2CuTi-type of structure is lower in energy than the Cu2MnAl one and more stable. The lattice constant of the former is a bit larger than the latter one, agreeing with experimental results. Ferromagnetism is observed in Mn2NiSb with both structures. Calculations give a total moment of 4.21 mu(B) for the Hg2CuTi-type of structure and 3.93 mu B for the Cu2MnAl-type one. These results fit the saturation magnetization at 5K quite well. The difference between the Curie temperatures of the bulk and ribbon samples is about 77 K.
