• Abstract Fe doping in Ni 2 Mn 1.5 In 0.5 results in suppression of the martensitic phase via two contrasting routes. In Ni 2 Mn 1.5 −  x Fe x In 0.5 , the martensitic phase is converted to a strain glassy phase, while in Ni 2 −  y Fe y Mn 1.5 In 0.5 , a cubic ferromagnetic phase results at the expense of the martensite. Careful studies of magnetic and structural properties reveal the presence of the impurity γ -(Fe,Ni) phase as the reason for the emergence of non-ergodic strain glassy phase when Fe is sought to be doped at Y/Z (Mn) sites of X 2 YZ Heusler alloy. Whereas attempts to dope Fe in the X (Ni) sublattice result in an A2 type antisite disorder that promotes a ferromagnetic ground state.
