The values of the magneto-crystalline anisotropy constants of the Ni2MnSn alloy have been determined at temperature 10 K under ambient and high hydrostatic pressure. The pressure-induced decrease of magnetization was confirmed and hence the significant nontrivial 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 has been observed in the martensite phase (orthorhombic structure) of the off-stoichiometric Ni2Mn1.43Sn0.57 alloy.
