摘　　要：Pr系MgCu2型超磁致伸缩材料由于其含有廉价轻稀土元素Pr,并且具有优良的磁致伸缩性能而受到广泛的关注。本文综述了这类材料在元素替代和成分调整方面的研究进展,以及制备工艺对材料的影响,并简要介绍了其单晶和取向多晶的制备方法。Pr-containing giant magnetostrictive materials with MgCu2-type possess high magnetoelastic properties due to low-cost light rare earth Pr, which show a good practical prospect. Much attention has been focused on the synthesis and the study of the magnetostrictive properties for these materials. In this paper, we review the recent developments of the studies based on elements substituting and composition adjusting as well as the preparation technique. The growth methods of single-crystal and oriented polycrystal are also mentioned.
