论文摘要
稀土氮化物构成了一系列结构上简单的$ intinsic $铁磁半导体，这是一种罕见的基本兴趣和应用潜力。在该系列中，有与旋转/轨道贡献相关的磁性特性。我们报告了在外交GD $ _x $ _x $ sm $ _ {1-x} $ n膜中SM和GD离子的自旋/轨道磁偶极对准的X射线磁圆二色性研究。 SM旋转对齐期望值$ \ langle s_ {z} \ rangle $可以通过GD/SM交换相互作用来增强，从而提供了有关角动量补偿点的组合物（其中膜的总角度动量，膜的总角度动量为零）。
The rare-earth nitrides form a series of structurally simple $intrinsic$ ferromagnetic semiconductors, a rare class of both fundamental interest and application potential. Within the series there is a wide range of magnetic properties relating to the spin/orbit contributions to the ferromagnetic ground states. We report an x-ray magnetic circular dichroism investigation of the spin/orbit magnetic dipole alignments of Sm and Gd ions in epitaxial Gd$_x$Sm$_{1-x}$N films. The Sm spin-alignment expectation value $\langle S_{z} \rangle$ is seen to be strengthened by the Gd/Sm exchange interaction, providing guidance concerning the composition for an angular momentum compensation point (where the volume-averaged total angular momentum of a film is zero).
