The temperature and magnetic field dependences of Ni-Mn-Ga polycrystals deformation are investigated. Ingots were prepared by arc-melting in argon atmosphere and further annealing. A training procedure (cycling across the martensitic transition point) for the two-way shape-memory effect was performed with Ni2.16Fe0.04Mn0.80Ga samples. Changes in sample deformations were noticed with changing the magnetic field at constant temperature. The first cycle deformation increment as compared with the initial value (in austenitic state, at zero field) in the course of the martensitic transition was 0.29%, and 0.41% and 0.48% for the second and third cycles, respectively.
