Abstract
The paper presents magnetization measurements and the scaling analysis of related power loss for a high-temperature magnetocaloric alloy (TC = 330 K). The measured hysteresis loops show anomalous behaviour near the temperature of 315 K, which may indicate the occurrence of additional phase transition. Power losses measured in different temperatures are analyzed using the scaling theory in order to determine the universal curves and the scaling exponents. The temperature dependence of scaling exponents confirms the existence of another phase transition at the temperature of 315 K, associated with an additional metallic phase in the alloy.
