摘要
采用磁控溅射方法在玻璃基片上制备了[BN/CoPt]_(n)/Ag薄膜,并在600℃退火30min。结果表明,周期数(n)和Ag底层厚度(x)对CoPt薄膜结构和磁性有着重要的影响,周期数适当时(n=5)有利于易磁化轴(c轴)垂直于膜面取向,从而具有高的垂直磁各向异性;Ag底层可以诱导L10-CoPt相的形成并使c轴垂直择优取向,且Ag适量时(x=10nm)其诱导效应最强。
[BN/CoPt]/Ag composite films are grown on glass 600℃for 30 rain.The magnetic properties and structures of and VSM.The results show that the perfect perpendicular substrates by using magnetron sputtering,then annealed at the thin films were studied by XRD,XP-2 films detector orientation has been achieved at appropriate number of repetition(n=5),and their perpendicular coercivities were higher than in-plane ones.Then the L10-CoPt phase was easily obtained by introducing Ag under layers,and the perfect(001)orientation can benefit from appropriate Ag under layer(x=10 nm).
