利用完全从头计算方法研究了磁性同双核团簇FeOFe和NiONi的激光诱导超快自旋翻转.氧原子降低了团簇的总对称性,导致自旋密度局域化。此外,所提出的自旋翻转的情况下,这两个集群表现出不同的模式匹配各自的电子结构。
Using fullyab initiocalculations we investigate the laser-induced ultrafast spin flip on the magnetic homodinuclear clusters FeOFe and NiONi. The oxygen atoms lower the total symmetry of the clusters inducing spin-density localization. Moreover, the proposed spin-flip scenarios on the two clusters exhibit different patterns matching their respective electronic structures.
