Their structure was found to be of the ThMn_(12) type with x=0.8 after appropriate annealing. The field dependence of magnetization was measured under range of 4.2 K to room temperature. The results indicate that Y(Mn_(1-x)Fe_x)_(12) appears antiferromagnetic when x=0.0, 0.2 or 0.4, in a spontaneous magnetization when x=0.6 and to become ferromagnetic or ferrimagnetic when x=0.8. The Curie point is above room temperature. 收稿日期: 1981-03-18      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 杨应昌 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1981/V17/I3/355 [1] Deportes, J., Givord, D., Lemaire, R. and Nagai, H., Physica, 86-88B (1977) , 69-70 (c).
