Their resistivity increases after long-term annealing under elevated temperature or after slowly cooled down from high temperature, but decreases with cold deformation. It seems that their anomalous thermo-electro-resistivity may be resulted from the formation of K-state. 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 何华春 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1981/V17/I1/97 No related articles found!
