Abstract

The structure and magnetic properties of ferromagnetic Tb_1-xGdxFe₂ system have been studied through the morphotropic phase boundary (MPB), a phase boundary between two ferroic phases of different crystal symmetry. Morphotropic phase boundary (MPB) has been studied extensively for its extraordinary enhancement effect in ferroelectrics. Based on same mechanism, we have designed a pseudobinary ferromagnetic system Tb_1-xGdxFe₂, of which the near-MPB composition Tb_1-xGdxFe₂ shows maximum magnetization under small field, and meanwhile dramatically the low magnetostriction. With synchrotron x-ray diffractometry, the crystal structure of TbFe₂-rich compositions is detected to be rhombohedral and that of GdFe₂-rich compositions is tetragonal below their curie temperatures. The near MPB composition Tb_0.1Gd_0.9Fe₂, shows the maximum magnetization among all available compositions and superposition of magnetostriction behavior of R and T phases. To find MPB phenomena in ferromagnets may provide a new route to design functional materials in other ferroic MPB systems.

伪二元铁磁Tb1−xGdxFe2体系的相变相界

通过两种不同晶型对称性的铁相之间的相界(morphphotropic phase boundary, MPB)研究了铁磁Tb1-xGdxFe2体系的结构和磁性。嗜形相边界(MPB)因其在铁电体中具有显著的增强作用而受到广泛的研究。基于相同的机制，我们设计了一个伪二元铁磁体系Tb1-xGdxFe2，其中近mpb成分Tb1-xGdxFe2在小磁场下磁化强度最大，同时磁致伸缩显著降低。在居里温度下，富tbfe2成分的晶体结构为菱形，富gdfe2成分的晶体结构为四边形。近MPB成分Tb0.1Gd0.9Fe2在所有成分中表现出最大的磁化强度和R相和T相磁致伸缩行为的叠加。在铁磁体中发现MPB现象可能为设计其他铁磁体中功能材料提供新的途径。
