  • Abstract
    Single crystals of Ni51Mn25.5Ga23.5 were grown in [001] direction of parent phase by the Czochralski method. A two-way thermoelastic shape memory with a larger spontaneous strain of 1.62% in the Ni51Mn25.5Ga23.5 crystal, noting without a prestress or an external magnetic field is reported. found. The results are discussed with reference to growth mechanism of single crystals and magnetic anisotropy produced by the preferential orientation of variants.
