Abstract
A solid-state refrigerator device has the potential to overcome the use of greenhouse effect-related gases or hazardous chemicals. Most of these devices work on the basis of magnetocaloric effect (MCE). Ce(Fe0.975Cr0.025)2 is an engrossing material to study MCE originating from paramagnetic (PM)–ferromagnetic (FM; second-order) transition and FM–antiferromagnetic (first-order) transition. In the present work, the MCE of Ce(Fe0.975Cr0.025)2 compound, prepared in Arc melting in an argon atmosphere, has been studied. Magnetic entropy change (∆SM) and the relative cooling power have been calculated from the M–H curves to characterize the MCE. Direct and inverse MCE are found to be linked with two different magnetic transitions in this compound.
期刊介绍：
The Bulletin of Materials Science is a bi-monthly journal being published by the Indian Academy of Sciences in collaboration with the Materials Research Society of India and the Indian National Science Academy. The journal publishes original research articles, review articles and rapid communications in all areas of materials science. The journal also publishes from time to time important Conference Symposia/ Proceedings which are of interest to materials scientists. It has an International Advisory Editorial Board and an Editorial Committee. The Bulletin accords high importance to the quality of articles published and to keep at a minimum the processing time of papers submitted for publication.
