用自旋偏振光电子能谱研究了由1-3个单层组成的V在Ag(001)上的薄膜的铁磁性。在30K和高达18kOe的外加磁场下测得的电子自旋极化在所有薄膜厚度下都小于2%。没有发现V在Ag(001)面上具有铁磁性的证据。现有的声称V在Ag(001)面上具有铁磁性的模型计算与实验不符。
Spin-polarized photoemission has been used as a probe of the ferromagnetism of thin films of V on Ag(001) consisting of 1--3 monolayers. The measured electron-spin polarization at 30 K and applied magnetic fields up to 18 kOe is less than 2% for all film thicknesses. No evidence for ferromagnetism of V on Ag (001) is found. Available model calculations claiming ferromagnetism of V on Ag(001) are in disagreement with the experiment.
