On heating the sputtered amorphous films, a β-Co transition metal phase forms first, no rare earth-transition intermetallic compound was observed till 750℃. This is believed to be related to the higher surface energy of thin films. 收稿日期: 1981-01-18      服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 张传历 刘壬宝 冯国华 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1981/V17/I1/105 [1] Kumar, K,, Das, D. and Wettstein, E., J.
