Abstract
Magnetization Of Ni52Mn24.4Ga23.6 and Ni52Mn24.2Ga2.3.8 magnetic shape memo ry alloys was measured as a function of magnetic field up to 50 kOe at temp eratures in the range 160-390 K. Anomalies of magnetic properties were obse rved not only at the temperature of martensitic transition Tm,. but also at a second transition temperature T-I < T-M. We assume that Ti is associated with an intermartensitic transformation.
