A sudden change of the relative coefficient was occurred with very distinguished extent about 2 times from the relative resistivity. It would like suggested that the anomalous Hall coefficient is an effective parameter for studying the crystallization process of amorphous magnetic alloy. 收稿日期: 1982-06-18      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 陈世林 支起铮 孙庭烈 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1982/V18/I6/752 1 Pugh, E.
