A perfect two-way shape memory effect (TWSME) with reversible strain of about 9% has been found in the high-temperature Ni 57.5 Mn 22.5 Ga 20.0 single crystal transforming into 2M non-modulated martensitic phase. Two thermal/mechanical treatment routes were utilized in the experimental procedures. T

We have examined the condition for the rearrangement of martensite variants (RMV) by magnetic field in a wide temperature range for three types of Ni-Mn-Ga ferromagnetic shape memory alloys: a Ni 2 MnGa with the 10M martensite, a Ni 2.02 Mn 1.09 Ga 0.89 (at.%) with the 14M martensite and a Ni 2.14 M
