N2 - Single crystal of the stoichiometric Ni2MnSn alloy (cubic L2(1) crystal structure) was prepared by the Czochralski method. The values of the magneto-crystalline anisotropy constant K-1 have been determined at temperature 10 K under ambient and high hydrostatic pressures, K-1 = + 0.17 x 10(4) and +1.96 x 10(4) J/m(3) (0.7 GPa), respectively. The pressure-induced decrease of magnetization was confirmed and hence the significant non-trivial increase of uniaxial anisotropy with increasing pressure points to a possible distortion of the cubic structure of the single crystal under hydrostatic pressure. Simultaneously, the more pronounced and pressure almost insensitive magneto-crystalline anisotropy, K-1 = + 9.1 x 10(4) J/m(3), has been observed in the martensite phase (orthorhombic structure) of the off-stoichiometric Ni2Mn1.43Sn0.57 alloy. The effect of a directional dependence of the Young modulus that was theoretically derived in the case of the Ni2MnSn-based alloys is discussed.
