Abstract

Magnetization of Ni52Mn24.4Ga23.6 and Ni52Mn24.2Ga23.8 magnetic shape memory alloys was measured as a function of magnetic field up to 50 kOe at temperatures in the range 160-390 K. Anomalies of magnetic properties were observed not only at the temperature of martensitic transition TM, but also at a second transition temperature TI < TM. We assume that TI is associated with an intermartensitic transformation.
