| Abstract: | The effect of ultrarapid quenching from melt and subsequent severe plastic deformation by torsion in Bridgman anvils on the temperatures of martensitic (T M) and magnetic (T C ) phase transitions in magnetic shape memory alloys has been investigated. The features of the crystal structure and magnetic, electric, and optical properties of Ni2MnGa-based alloys with different degrees of structural ordering are discussed. The effect of doping with copper and cobalt on the properties of nonstoichiometric Ni50Mn28.5Ga21.5 alloy is considered. |
