AbstractThe structural and magnetoelastic properties of (Tb0.3Dy0.7)(1-x)(Pr0.5Nd0.5)(x)Fe-1.93 (0 <= x <= 0.20) poly-crystalline alloys have been investigated by means of X-ray diffraction (XRD), a vibrating sample magnetometer and a standard strain gauge technique. A single (Tb, Dy, Pr, Nd)Fe-2 Laves phase with a cubic MgCu2-type structure is formed when x <= 0.12, while a small amount of impurities appear when x >= 0.15. The easy magnetization direction at room temperature is detected toward < 111 > axis. The analysis of XRD, magnetization and magnetostriction shows that the Pr and Nd elements joint introduction into (Tb, Dy)Fe-2 system can reduce the magnetocrystalline anisotropy and improve the magnetoelastic properties. The (Tb0.3Dy0.7)(0.88)(Pr0.5Nd0.5)(0.12)Fe-1.93 alloy exhibits a high low-field magnetostriction lambda(a) (similar to 314 ppm/1 kOe), a large spontaneous magnetostriction coefficient lambda(111) (similar to 1710 ppm), a giant saturation magnetostriction lambda(S) (similar to 1060 ppm) and the low magnetocrystalline anisotropy at room temperature, and may make it a promising candidate for magnetostriction applications.
