In Ni2 MnGa (cubic structure of L 21 type) a first order martensitic structural transition, from the parent cubic (austenitic) phase to a low temperature complex tetragonal structure, takes place at TM =202 K, and ferromagnetic order in the austenitic phase sets at TC =376 K. In this work, the Mn sites in Ni2 MnGa have been partially substituted with magnetic Co and nonmagnetic Cu, and the influence of these substitutions on the structural and magnetic properties of Ni2 Mn1-x Mx Ga (M=Co and Cu) have been studied by XRD and magnetization measurements. X-ray diffraction patterns indicate that the Co doped system possess a highly ordered Heusler alloy L 21 type structure for 0.05
