Low twinning stress 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 twinning stress. See also https://doi.org/10.1016/j.jmrt.2021.07.081
