Abstract

Morphotropic phase boundary (MPB), separating two ferroic phases of different crystal symmetries, has been studied extensively for its extraordinary enhancement of piezoelectricity in ferroelectrics. Based on the same mechanism, we have designed a magnetic MPB in the pseudobinary ferromagnetic system of Tb_1-xGd_xFe₂ and the corresponding crystal structure, magnetic properties, and magnetostriction are explored. With the synchrotron x-ray diffractometry, the structure symmetry of TbFe₂-rich compositions is detected to be rhombohedral (R) and that of GdFe₂-rich compositions is tetragonal (T) below T_c. With the change of concentration, the value of magnetostriction of the samples changes monotonously, while the MPB composition Tb_0.1Gd_0.9Fe₂, which corresponds to the coexistence of R and T phases, exhibits the maximum magnetization among all available compositions and superposition of magnetostriction behaviour of R and T phases. Our result of MPB phenomena in ferromagnets may provide an effective route to design functional magnetic materials with exotic properties.
