Observation of an Extensive Curie Temperature Window and Synergic Multicaloric Effects in NiMnCuGaSn Alloys

ACS Applied Electronic Materials, Journal Year: 2024, Volume and Issue: 6(6), P. 4440 - 4448

Published: May 15, 2024

The study of multicaloric effects in Heusler alloys has attracted increasing research interest, fueled by their potential applications solid-state refrigeration and energy conversion technologies. Despite the promising aspects, challenges such as limited operating temperature range large hysteresis have hindered optimal device performance. Herein, introducing a Cu/Sn co-substitution strategy, Curie window for synergic magnetostructural transformation is extended from 244 K to 313 customized NiMnCuGaSn alloys, along with substantial increase entropy change. Crucially, employing combined approach magnetic-field-stress loading zero-field-stress unloading significantly reduces stress enhances reversibility transformation, resulting significant adiabatic change 4.7 at relatively low critical stress. This underscores an efficient method enhance caloric responses, paving way advances cooling
