Title: Characterization of the Magnetocaloric Effect in RMn6Sn6 including High Entropy Alloys
(Submitted on 17 Aug 2023 (v1), last revised 14 Feb 2024 (this version, v2))
Abstract: We present a comprehensive study of the magnetocaloric effect (MCE) in a family of kagome magnets with formula RMn6Sn6 (R=Tb, Ho, Er, and Lu). These materials have a small rare-earth content and tunable magnetic ordering, hence they provide a venue to study the fundamentals of the MCE. We examine the effect of different types of order (ferrimagnetic and antiferromagnetic) and the presence of a metamagnetic transition on the MCE. We extend the study to high-entropy rare-earth alloys of the family. Our results suggest several guidelines for enhancing the MCE in tunable magnetic materials with a small rare-earth content.
