The magnetic properties of the samples were studied by a micropro cessor-controlled vibrating-sample magnetometer. When the charging Ar pressure PAr=2.67 Pa, an oscillation between ferromagnetic and antiferromagnetic coupling with the thickness of Cr layers was found, and the spontaneous magnetization Ms remains constant basically. When PAr=0.67 Pa, the value of Ms shows an oscillatory behaviour, which may be related to the oscillatory variation of the paramagnetic component in the ferromagnetic layers. Key words： muiltilayered film    ferromagnetic coupling    antiferromagnetic coupling 收稿日期: 1998-04-18      基金资助:国家自然科学基金!59392800 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 娄坚鑫 颜世申 刘宜华 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1998/V34/I4/412 1 Grunberg P, Schreiber R, Pang Y, Brodsky M B, Sowers H.
