Thermoelastic martensitic transformations were investigated under cooling/heating under compressive load in <011>-, <123>-oriented NiMnGa single crystals annealed at a 1273 K for 1 hour followed by slow cooling. It is shown that the reversible strain at shape memory effect and the value of the thermal hysteresis ΔT depend on the orientation of the crystal axis: in the <011>-oriented single crystals the maximum reversible strain is ε = 4.1 %, and the maximum thermal hysteresis ΔT = 60 K, and in <123>-oriented single crystals ε = 3.2 %, and ΔT = 35 K.
