Abstract:

This paper reports on the results of investigations into the structure of martensite and the electronic and magnetic properties of Ni2 + x Mn1 - x Ga alloys in the concentration range 0.12 a parts per thousand currency sign x a parts per thousand currency sign 0.39. The concentration dependences of the critical temperatures and the anomalous behavior of the degree of tetragonal distortion of the martensite have been discussed, as well as the changes in the parameters characterizing the electronic and magnetic subsystems in the thermoelastic martensitic transition L2(1) a dagger{''} M, which occurs in atomically ordered L2(1)-type alloys upon doping in the range 0.12 a parts per thousand currency sign x a parts per thousand currency sign 0.39 at different temperatures. The temperature and concentration dependences of the magnetic properties have been determined for the state of the single-phase L2(1) austenite (at T > T (C) and A (f)) and martensite (at T < T (C) and M (f)), which undergoes the transition from a modulated 10M- or 14M-type structure to a nonmodulated (NM) tetragonal structure.
