Abstract
The effect of ultrarapid quenching from the melt and severe plastic torsional deformation under high pressure on the crystalline structure and the electrical, optical, and magnetic properties of a Ni2.16Mn0.84Ga alloy was studied. The electrical properties are discussed in terms of the Mott two-band model. The peculiarities of the magnetic properties are associated with the magnetism of itinerant electrons. The optical properties correlate with the variations in the electronic spectrum upon disordering of the alloy that follow from the results of the available energy-band-structure calculations.
