Abstract
We have synthesized a new crystallographically ordered quaternary Heusler alloy, MnNiCuSb. The crystal structure of the alloy has been determined by Rietveld refinement of the powder xray diffraction data. This alloy crystallizes in the LiMgPdSb type structure with F4¯3m space group. MnNiCuSb is a ferromagnet with a high TC ~ 690K and magnetic moment of 3.85µB/f.u. Besides this we have also studied two other off-stoichiometric compositions; one Cu rich and other Ni rich (MnNi0.9Cu1.1Sb and MnNi1.1Cu0.9Sb) which are also ferromagnets. It must be stressed that MnNiCuSb is one of the very few known, non-Fe containing quaternary Heusler alloys with 1: 1: 1: 1 composition.
