We describe the influence of inserted oxygen atoms on the structural and magnetic properties of a [Co/Pt]n multi-layer matrix. The correlation of magnetic properties with oxygen gas flow rate was studied as an alternative perpendicular medium in spin transfer torque magnetic random access memory applications. Experimental analysis suggests that the addition of a small amount of oxygen atoms into the [Co/Pt]n multi-layer matrix leads to a high coercivity and proper magnetization performance, together with high thermal stability. Finally, the nature of the improved perpendicular medium behaviors is also discussed.
我们描述了插入的氧原子对[Co/Pt]n多层矩阵的结构和磁性的影响。作为自旋转移矩磁随机存取存储器应用中的一种替代垂直介质,研究了磁性与氧气流量的相关性。实验分析表明,向[Co/Pt]n多层矩阵中添加少量氧原子会导致高矫顽力和适当的磁化性能,以及高热稳定性。最后,还讨论了改进的垂直介质行为的本质。
