同步辐射透过磁化铁时，在K吸收边以上的能量下，左右圆偏振的相对差异为10− 4的数倍。近边光吸收的自旋依赖性与未占据带的自旋密度之差成正比。在扩展的吸收区域高达200 eV以上的费米能级观察到一个小的自旋相关的吸收，因此预计将提供信息的磁性附近的吸收原子。
The transmission of synchrotron radiation through magnetized iron at energies above the K-absorption edge shows relative differences for right and left circular polarization of several times 10− 4. The observed spin dependence of the near-edge photoabsorption is proportional to the difference of the spin densities of the unoccupied bands. In the extended absorption region up to 200 eV above the Fermi level a small spin-dependent absorption is observed and thus is expected to give information on the magnetic neighborhood of the absorbing atom.
