非共振磁 X 射线散射 (NRXMS) 是一种独特的工具，可以分离自旋和轨道矩密度对总磁化密度的贡献。该方法已成功应用于简单过渡金属氧化物：MnO、CoO和CuO。通常的习惯是考虑这些氧化物的轨道矩被立方晶体电场猝灭。然而，我们确实观察到 CoO 和 CuO 的非消失轨道矩。轨道矩的部分重建与自旋轨道耦合有关。
Non-resonant magnetic X-ray scattering (NRXMS) is a unique tool allowing the separation of the spin and orbital moment density contributions to the total magnetization density. This method has been successfully applied to the simple transition metal oxides: MnO, CoO and CuO. It is common habit to consider the orbital moment of these oxides to be quenched by the cubic crystal electric field. We do, however, observe non-vanishing orbital moments in the case of CoO and CuO. The partial re-establishment of the orbital moment is related to spin-orbit coupling.
