摘 要：Ag/[BN/CoPt]5/Ag and [BN/Ag/CoPt]5/Ag thin films were deposited on glass substrates by magnetron sputtering and then annealed in vacuum at 600 ℃ for 30 min.The structures and magnetic properties of CoPt/BN multilayer films were investigated as a function of Ag layer thickness.It was found that the face-centered tetragonal （fct） （001） texture of CoPt was improved greatly by introducing the Ag toplayer or sublayer together with an Ag underlayer.Good （001）-oriented growth,low intergrain interactions as well as high perpendicular anisotropy can be obtained in the Ag（3 nm）/[BN（2.5 nm）/CoPt（3 nm）]5/Ag（7 nm） and [BN（2.5 nm）/Ag（2 nm）/CoPt（3 nm）]5/Ag（10 nm） films,which become potential candidates for ultrahigh density magnetic recording media.
