Abstract (EN): Rare earth orthochromites (RCrO3) have attracted much interest in recent years due to their physical properties which arise from the orthorhombically distorted perovskite structure. They also show great potential application as multifunctional materials. In this work we present the results of structural, dc magnetisation measurements and magnetocaloric properties for YCrO3 hard magnet. The magnetocaloric effect was investigated by means of field dependence magnetisation measurements in a temperature range from 98 K to 182 K. The magnetic entropy change, -Delta S-M = 036J kg(-1) K-1, and the refrigerant capacity, R-C = 7.1 J kg(-1), was obtained near the transition temperature T-N = 140 K, for applied fields up to 50 kOe.
