Abstract

Magnetization of Ni₅₂Mn_24.4Ga_23.6 and Ni₅₂Mn_24.2Ga_23.8 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 T_M, but also at a second transition temperature T_I < T_M. We assume that T_I is associated with an intermartensitic transformation.
