项目摘要
Ferromagnetic tunnel junctions (MTJs) are the major device in spintronics, which are used for read heads of hard disk drives (HDDs) and magnetic random access memories (MRAMs). The coherent tunnel effect is of particular importance in enhancing the performance of MTJs, but the electrode and barrier materials usable for the coherent tunneling have been limited. In this study, for the first time we have successfully developed crystalline MgAlO and AlO barriers that are grown epitaxially on NiFe(111). It is expected that the new barriers brings about the coherent tunnel effect and resulting high magnetoresistance for MTJ structures with the unconventional crystallographic orientation.
铁磁隧道连接(MTJ)是Spintronics的主要装置,用于硬盘驱动器(HDDS)和磁随机访问记忆(MRAM)的读取头。相干隧道效应在增强MTJ的性能方面尤其重要,但是可用于相干隧道的电极和屏障材料受到限制。在这项研究中,我们首次成功地开发了在Nife上外上期生长的晶体MGALO和ALO屏障(111)。预计新障碍会带来连贯的隧道效应,并带来非常规晶体学取向的MTJ结构的高磁磁性。
