多次散射的自旋极化相对论版本或电子结构计算的Korringa-Kohn-Rostoker方法已被用于研究自由和支撑过渡金属团簇的电子和磁性。给出了自由Fe和FePt团簇中自旋和自旋轨道诱导的轨道磁矩的相应结果。与相应的体积值相比,这两个系统的自旋和轨道矩都有明显的增强,而相应的体积值随着团簇大小的增加而振荡地减小。对沉积在Pt(111)表面的小Co团簇的相应研究也表明,团簇的大小和形状对磁性能有很强的依赖性。将我们的理论结果与现有的实验数据进行比较,得出了相当令人满意的结果。
The spin-polarized relativistic version of the multiple scattering or the Korringa–Kohn–Rostoker method for electronic structure calculations has been used to study the electronic and magnetic properties of free and supported transition metal clusters. Corresponding results are presented for the spin- and spin–orbit-induced orbital magnetic moments in free Fe and FePt clusters. For both systems a pronounced enhancement is found for the spin as well as for the orbital moments compared with the corresponding bulk value which diminishes in an oscillatory fashion with increasing cluster size. Corresponding investigations on small Co clusters deposited on a Pt (111) surface also revealed a strong dependence of the magnetic properties on the cluster size and shape. A comparison of our theoretical results with available experimental data led to rather satisfying agreement.
