  The temperature and magnetic field dependencies 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 Ni$_{2.16}$Fe$_{0.04}$Mn$_{0.80}$Ga samples. Changes in sample
deformations were noticed with changing the magnetic field at a constant
temperature. The first cycle deformation increment as compared with the initial
value (in the 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.
