论文摘要
稀土的稀有合金在理解磁现象中起着至关重要的作用。在这里，我们对光金属中稀释的4F稀土杂质的基态建模。当4F子壳打开（但没有半填充）时，自旋轨道耦合烙印在稀土原子周围传导电子的旋转电荷电流。电流振荡量的符号和振幅类似于rkky自旋极化。我们计算可观察的效果，即当前涡流和骑士移位产生的oersted场。
Dilute alloys of rare earths have played a vital role in understanding magnetic phenomena. Here, we model the ground state of dilute 4f rare-earth impurities in light metals. When the 4f subshells are open (but not half-filled), the spin-orbit coupling imprints a rotational charge current of conduction electrons around rare-earth atoms. The sign and amplitude of the current oscillate similar to the RKKY spin polarization. We compute the observable effect, namely the Oersted field generated by the current vortices and the Knight shift.
