摘　　要：用双对向靶溅射方法制备了两种成分的[Co（1.2nm）／Cu（tCu）]（tCu＝10nm，3.4nm）纳米多层膜分别用TEM和TG方法研究了[Co／Cu]多层膜结构和磁性随温度的变化.结果表明：tCu＝10nm的多层膜样品出现了两个磁性转变点。[Co(1.2nm) / Cu(tCu)](tCu= 1.0 nm, 3.4 nm) nano-multilayers were preparedby dual-facing target sputtering method. The multilayers were then annealed in silu by TEMand TG methods to investigate the changes of the microstructure and magnetism. Twoferromagnetic phases, hop Co and Co-Cu solid solution with lattice parameter of around0.358 nm, existed in tCu= 1.0 nm multilayer and were related to two magnetictransformations.
