In the Ni_2,15Mn_0,81Fe_0,04Ga alloy magnetic control of the one-way shape memory effect has been observed, that is restoration of the shape of a formerly deformed sample at constant temperature through the magnetic field induced martensite - austenite structural phase transition. The maximal deformation observed is 3 per cent.
