摘要:
磁致伸缩材料是制造换能器和传感器的重要磁性功能材料。此前，在铁电材料中，通过将材料成分控制在准同型相界，获得了大压电效应。因此根据铁磁与铁电材料表现出的物理效应的相似性，可以期待在铁磁材料中构建准同型相界，获得磁场导致的奇异应变特性。本文归纳了已发现的基于准同型相界而构建的Laves相RT2稀土合金体系Tb1-xDyxCo2，Tb1-xGdxCo2和Tb1-xGdxFe2，总结了磁致伸缩效应和其他物理性能与准同型相界的关系，可为设计新型磁致伸缩材料提供思路和依据。
Abstract:
Magnetostrictive materials are important magnetic functional materials that are widely used in transducers and sensors. Previously, large piezoelectricity was obtained via controlling the composition of ferroelectric materials around morphotropic phase boundary (MPB). Based on the physical parallelism between ferroelectrics and ferromagnetism, it is expected of anomalous field-induced strain effect for magentic materials at MPB. In this article, three types of recently reported ferromagnetic MPB systems are reviewed, and the relationships between various properties and MPB are summarized, which can provide new insights for developing highly magneto-responsive materials.
