摘要
在凝聚态物理领域,随着高压实验技术不断取得进步,探究材料在高温、高压、强磁场等环境下的物理性质已成为切实可行且行之有效的研究路径。锰酸盐的晶体结构和物理化学性质相对稳定,具有成本较为低廉的优势,通过调节居里温度可以使锰酸盐在室温附近表现出合适的磁热性能。本文概述了近年来极端条件下不同带宽类型掺杂锰酸盐材料磁热效应的研究进展,重点强调了压力在调控磁性材料的磁有序强度和温度、相变特征及磁热性能等方面的特殊作用。
In the field of condensed matter physics,with the continuous progress of high pressure experimental technique,it has become a practical and effective research path to investigate the physical properties of materials under extreme conditions such as high temperature,high pressure and strong magnetic field.The crystal structure and physicochemical properties of manganates are relatively stable,and they have the advantage of lower cost.By adjusting the Curie temperature,manganates can exhibit suitable magnetocaloric effects near room temperature.This paper summarizes the researches of magnetocaloric effect of various bandwidth types of doped manganate materials under extreme conditions in recent years,where the role of pressure is emphasized in regulating the intensity and temperature of magnetic ordering state,the nature of magnetic phase transitions and the magnetocaloric properties of magnetic materials.
