通过磁康普顿剖面技术探测了单晶铁磁钆的自旋相关动量密度。与电子结构计算的比较表明，局部自旋密度近似足以描述磁性康普顿分布。此外，松饼罐轨道处方的线性组合优于全势方法。我们发现针对实验态密度的测试理论是有问题的。我们的计算还表明自旋密度对 5p 电子的处理很敏感。
The spin-dependent momentum density of single-crystal ferromagnetic gadolinium was probed by the magnetic Compton profile technique. Comparison with electronic structure calculations indicate that the local spin-density approximation is adequate for describing the magnetic Compton profiles. Furthermore, the linear combination of muffin-tin orbitals prescription compared favourably with a full-potential method. We find that testing theory against the experimental density of states is problematic. Our calculations also indicate that the spin density is sensitive to the treatment of the 5p electrons.
