Abstract

Morphotropic phase boundary (MPB) have aroused wide interests due to the exotic properties exhibited by the compositions around MPB [Tb_1-xDy _x Co₂, PRL 104, 197201 (2010); Tb_1-xDy _x Fe₂, PRL 111, 017203 (2013)]. By combining the two MPB compositions Tb_0.3Dy_0.7Co₂ and Tb_0.3Dy_0.7Fe₂, we designed a pseudo-binary system Tb_0.3Dy_0.7(Co_1-xFe_x)₂. The phase diagram is determined from the temperature spectra of magnetic susceptibility and magnetization. A Griffiths-like phase appears above the Curie temperature and gradually vanishes as the Fe content increases to x = 0.8. Magnetic hysteresis and magnetoelastic behavior are also investigated. Compared with the Terfenol-D composition x = 1.0, x = 0.8 exhibits higher Curie temperature (707 K) and comparable magnetostriction (818 ppm), which may be used in the sensors or transducers at high temperature.
