Ag层厚度对FePd薄膜的结构和磁性能的影响
Effect of thickness of Ag layer on the structure and magnetic properties of FePd films
摘要
Abstract
A series of FePd based alloy films were deposited on glass substrates by DC magnetron sputte-ring .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 lay-er could accelerate phase transition from FCC (face-centered cubic) to FCT (face-centered tetragonal) in films and greatly enhance the coercivity of FePd films .Compared Ag/FePd with FePd/Ag films ,some samples of Ag/FePd films have highly preferred orientation .The magnetic easy axis of the crystallites in Ag/FePd film is in-plane of substrate .When the thickness of Ag toplayer is equal to 31 nm ,the film has a very large in-plane coercivity of 2 .8 kOe and a very low out-of-plane coercivity of 1 .04 kOe .关键词
