Abstract

This manuscript explores the magnetocaloric properties of the antiperovskite compound AsNCr3, emphasizing its potential for sustainable refrigeration applications. Employing a combination of phenomenological modeling and density functional theory, the research reveals that the material’s low magnetization, arising from antiferromagnetic spin alignment, contributes to reduced hysteresis losses and enhanced thermal stability. Key findings include moderate entropy changes, a relatively narrow operational temperature span, and field-dependent phase transitions, indicating suitability for precise thermal management. The insights offer a pathway to designing efficient, environmentally friendly refrigeration systems based on low-magnetization materials.
