摘要: The ac-susceptibility X ac of ultrathin Co and Ni layers coupled indirectly across a Cu spacer layer is measured as function temperature in situ UHV. Depending on the strength interlayer exchange interaction one or two maxima susceptibility are recorded near respective Curie temperatures bare films. Using element specificity X-ray magnetic circular dichroism (XMCD) separate temperature-dependent magnetization curves for vanishing at different temperatures. higher systems. Due to lower characteristic cannot be interpreted thermodynamic phase transition.
