A unified physical mechanism for martensitic phase transition and ductility in Ni–Mn-based ferromagnetic shape memory alloys: the case of Cu-doped Ni2MnGa

Taking Cu-doped Ni 2 MnGa alloys as an example, the unified physical mechanism for martensitic phase transition and ductility in Ni–Mn-based ferromagnetic shape memory alloys was investigated theoretically.
