Abstract

For a quarter-century since the discovery of the giant magnetocaloric effect (MCE), the world scientific community has paid great attention to comprehensive studies of magnetically ordered compounds with a first-order magnetostructural phase transformation. The interest in the study is due both to the potential application of the MCE in magnetic cooling technology and the need to provide a deeper understanding of the fundamental concepts of the problems and mechanisms underlying the magnetostructural transition. This review covers the thermodynamic foundations of the MCE, a comparative analysis of magnetocaloric materials with magnetostructural phase transitions, and outlines the phenomenological and microscopic models for predicting magnetocaloric properties developed by the global scientific community over the past 20 years.

磁热材料研究的现代理论方法综述

摘要

自巨磁热效应(MCE)发现以来的 25 年里,世界科学界一直高度重视对具有一级磁结构相变的磁性有序化合物的综合研究。对这项研究的兴趣是由于 MCE 在磁冷却技术中的潜在应用,以及需要更深入地理解磁结构转变背后的问题和机制的基本概念。这篇综述涵盖了 MCE 的热力学基础,对具有磁结构相变的磁热材料进行了比较分析,并概述了过去 20 年来全球科学界开发的用于预测磁热特性的现象学和微观模型。
