摘要：

Magnetic and magnetostrictive properties have been investigated for amorphous (Tb0.27Dy0.73)(FexCo1-x)(2) thin films. An increase in the 3d magnetic moment and Curie temperatures higher than 550 K due to the enhancement of T-T interactions (T = transition metal) in substituted (Fe,Co) alloys were found. A well defined in-plane anisotropy is created by magnetic field annealing for the Go-rich films. A large magnetostriction of 480 x 10(-6) was developed in 1.8 T magnetic field and 350 x 10(-6) in low fields of 0.06 T for films with x = 0.47 after magnetic field annealing. The differing roles of Fe and Co atoms in the magnetization process have also been investigated.
