Nd_2Fe_(14)B/α-Fe交换耦合双层薄膜磁性能 伍静1,张敏刚1,闫晓燕1,杨丽丽1 (1.太原科技大学材料科学与工程学院,太原,030024) 摘要:利用微磁学理论模拟计算了Nd_2Fe_(14) B/α-Fe交换耦合双层膜的磁滞回线,并对双层膜体系的剩磁,矫顽力,最大磁能积与软磁层厚度的关系进行了研究.结果显示,软磁层厚度小于临近尺寸时,磁滞回线为矩形,双层膜完全耦合;软磁层厚度与磁性能的关系表明,随着软磁层厚度的增加,剩磁和最大磁能积先增大后减小,而矫顽力单调下降. 关键词:微磁学; 交换耦合; 剩磁; 矫顽力; 磁能积; rrucromagnetic; exchange-coupling; remanence; coercivity,energy products; [全文内容正在添加中] ......
