| contents | The local environment of Mn atoms in stoichiometric Ni-Mn-Ga Heusler alloys was investigated using Nuclear Magnetic Resonance (NMR) and interpreted with the help of Density Functional Theory (DFT) methods. In cubic austenite, the significant amount of structural defects was observed in \mn NMR experiments and interpreted using DFT calculations as individual antisite defects or defects accompanying anti-phase boundaries. Combined NMR and DFT analysis provides a consistent microscopic description of local disorder in Ni-Mn-Ga. |
