A series of FePd based alloy films were deposited on glass substrates by DC magnetron sputtering.In order to find the role of the Ag layer in disorder-order of FePd film,it was studied that the Ag layer effected on Agx/FePd(67.5 nm)(x=3.875、7.75、15.50、31、38.75 nm)and FePd(67.5 nm)/Agx(x=7.75、15.50、31 nm)films annealed at 600 ℃ for different time.The results showed that the Ag layer could accelerate phase transition from FCC(face-centered cubic)to FCT(face-centered tetragonal)in films and greatly enhance the...
