论文摘要
电子自旋进液和滤波在磁性薄膜的分子场中测量。进行的实验室实验实验允许注射具有0.8至1.1 eV之间的电子，在自旋进动实验中从未探索过能量范围。虽然过滤角与以前在更高的电子能量下测得的报道的值一致，但可以测量COFE的自旋进动角为2.5°，而每纳米膜厚度的CO中的旋转进度为0.7°，比以前在7 eV时测量的型号小30倍。带结构效应和层粗糙度负责这些小的进动角值。
Electronic spin precession and filtering are measured in the molecular field of magnetic thin films. The conducted lab-on-chip experiments allow injection of electrons with energies between 0.8 and 1.1 eV, an energy range never explored up to now in spin precession experiments. While filtering angles agree with previous reported values measured at much higher electron energies, spin precession angles of 2.5° in CoFe and 0.7° in Co per nanometer film thickness could be measured which are 30 times smaller than those previously measured at 7 eV. Band structure effects and layer roughness are responsible for these small precession angle values.
