【摘要】 磁致冷作为一种新的制冷方式而受到广泛的重视。详述了低温区和高温区的磁致冷工质材料的研究过程及现状,并指出多种成分的复合工质可实现宽温区磁致冷;稀土合金及具有巨磁阻效应的钙钛矿陶瓷材料可能是研究可实际应用的室温区磁致冷材料的新方向。更多还原

【Abstract】 As a new cooling techmgue magnetic refrigeration has been intensively studied. This paper presents a description of the current status of development and research on magnetic refrigeration in low and high temperature range,and suggests that combination of different kinds of matreials will widen the refrigerate temperature; rare-earth alloy and ceramics with giant magnetoresistence may be promising room-temperature magnetic refrigeration materials更多还原
