Effect of crystal quality on twinning stress in Ni–Mn–Ga magnetic shape memory alloys

Effect of crystal quality on twinning stress in Ni–Mn–Ga magnetic shape memory alloys

Low twinning stress (TS) is a prerequisite for magnetic shape memory functionality in ferromagnetic martensites. We compare Ni50Mn28Ga22 (nominal at.%) single crystals from four different producers to reveal the effect of crystal quality on the TS. Near the reverse martensite transformation, the TS...
