摘要：

The large magnetocaloric effect (MCE) of Gd metal has enabled us to successfully test a near-room temperature proof-of-principle apparatus and to show that magnetic refrigeration (MR) is a viable and competitive technology with gas compression/expansion refrigeration. A search for new materials with improved magnetocaloric properties has led to the discovery of the giant MCE in Gd-5(SixGe1-x)(4) alloys. These intermetallic compounds should make MR even more efficient and will open the doors to new possibilities for MR. The future prospects of magnetic refrigeration as an important rare earth market are discussed.
