Abstract: We have synthesized a new crystallographically ordered quaternary Heusler alloy, MuNiCuSb. The crystal structure of the alloy has been determined by Rietveld refinement of the powder X-ray diffraction data. This alloy crystallizes in the LiMgPdSb type structure with F (4) over bar 3m space group. MnNiCuSb is a ferromagnet with a high T(c similar to)690 K and magnetic moment of 3.85 mu B/f.u. Besides this we have also studied two other off-stoichiometric compositions; one Cu rich and the other Ni rich (MnNi0.9Cu1.1Sb and MuNi(1.1)Cu(0.9)Sb) 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. (C) 2015 Elsevier B.V. All rights reserved.
