Structure in two Ni2MnGa alloys, that exhibit large magnetic field induced strain in martensite phase, was studied with neutron diffraction in temperature range 4K-354K. It is found that lattice parameters in martensite notably change with temperature. The magnetic field induced strain value decreases/rises with the rise/decrease of temperature according to the change of (1-c/a) in martensite phase. The critical value of the magnetic field for activation of the twin's boundary motion decreases with increasing temperature.
