研究了CO吸附对Cu（001）表面Fe膜磁性能的影响及其与膜厚的关系。CO吸附不影响2ml Fe膜的磁性能，但诱导了3ml和4ml Fe膜的自旋取向由面外磁化向面内磁化。它还会导致磁化强度的降低，这可以归因于表面磁化强度的降低。6和8ml的铁膜因CO吸附而失去磁性。讨论了对这些复杂磁行为的可能解释。
Effects of CO adsorption on the magnetic properties of Fe films on Cu(001) were studied atas a function of the film thickness. CO adsorption does not affect the magnetic property of 2 ML Fe film but induces the spin reorientation from out-of-plane to in-plane magnetization for 3 and 4 ML films. It also causes the decrease of magnetization, which can be attributed to the reduction in surface magnetization. Fe films of 6 and 8 ML lose their magnetization by CO adsorption. Possible interpretations for these complicated magnetic behaviors are discussed.
