Investigation on the preference of the martensitic structure in off-stoichiometric Ni-Mn-In alloys by first-principle calculations

•The tetragonal distortion was employed to predict the preferred stable structure under the effect of the excess Mn in the Ni-Mn-In alloys by first-principle calculations using EMTO-CPA with magnetic structure optimization.•To find out more accurate preference of the martensite structure in off-stoi...
