SOLID-PHASE REACTION AND MAGNETISM IN ANNEALED [CO/Cu] MULTILAYERS
退火[Co＼Cu]多层膜的固相反应与磁性

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.
