| 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 |
