Abstract. In this paper, based on the results of experimental studies of the temperature dependences of magnetization of Ni51–xMn33.4In15.6Vx (x = 0; 0.1; 0.3; 0.5; 1 at.%) and Ni46Mn41In13 Heusler alloys in weak and strong magnetic fields, a phenomenological model is proposed that explains the features of phase transitions, namely: a decrease in the temperature of the first-order metamagnetostructural martensitic phase transition under the influence of a magnetic field and the degree of alloying of the alloy. The results of accurate analytical calculations and numerical modeling are presented and compared.
Key words: Heusler alloys, martensitic transformation, phase magnetizations, metamagnetostructural phase transition, interaction of phase transitions.
