摘要

The structure and inagnetostriction of Dy_(0.9-x)Tb_(x)Pr_(0.1)Fe_(1.85) and Dy_(0.9-x)Tb_(x)Pr_(0.1)(Fe_(0.95)Al_(0.05))_(1.8) alloys were investigated.These alloys are substantially single phase with MgCu2-type cubic structure.The lattice parameter and Curie temperature of Dy_(0.9-x)Tb_(x)Pr_(0.1)(Fe_(0.95)Al_(0.05))_(1.8) alloys increase steadily with increasing Th content.Tb dependence of magnetostnction in various applied fields for poly crystalline Dy_(0.9-x)Tb_(x)Pr_(0.1)Fe_(1.85) alloys exhibits a peak at x=0.25.The magnetostric-tion of polycrystalline Dy_(0.9-x)Tb_(x)Pr_(0.1)(Fe_(0.95)Al_(0.05))_(1.8) alloys in high applied fields(H>160 kA/m)and in low applied Helds(H≤160 kA/m)exhibits a peak at x=0.3 and x=0.25,respectively.
