Magnetization and coercivity in Co/Pt multilayers with constant total Co layer thickness NIE Ying(聂 颖)1, 2 , YANG Xin(杨 鑫)2 , ZHANG Pang(张 鹏)1, SANG Hai(桑 海)1 1. National Laboratory... components parallel and perpendicular to the applied field. A dependence of the coercivity of Co/Pt multilayers on the Co layer thickness was reported, in which the total thickness of Co layers kept......

microscope (SPM) were applied to study the magnetic properties and microstructure. Magnetic properties such as coercivity(Hc) are strongly dependent on the thickness of Ag and the annealing temperature. When the thickness of Ag underlayer is 20nm, the coercivity reaches the maximum of 2200×79.578A/m. The XRD patterns show that the CoCrPt films are hcp structure lying on the film plane. The SPM images show......
anisotropy energies, Zeeman energies and demagnetizing energies show that the demagnetizing field is the main factor to decide the coercivity in medium. The granular-type film has a smaller... film; micromagnetics; coercivity 垂直磁记录技术最早由19世纪的丹麦科学家VALDEMAR提出,到了1976年垂直......
-rich regions, and the MnBi phase was formed in homogeneous regions with a balanced composition between Mn and Bi. A ferromagnetic hysteresis loop was obtained in the ground powder with a coercivity of 40 kA/m. Subsequent annealing at 553 K under a pressure of 414 kPa for 12 h enhanced the MnBi phase with extended regions of balanced composition. It follows that the coercivity was increased to 60 kA......
