Notes:
The magnetic exchange anisotropy of a series of single crystal Co1−xMnx/Mn bilayers (0≤x≤ 0.37) is studied as a function of the Mn content. By means of ferromagnetic resonance, it is found that the exchange anisotropy shows up when 0.30≤x≤0.37 and disappears when x≤0.20 at room temperature. The phenomenon of Mn enrichment is observed at the Co–Mn surface by the technique of varying angle x-ray photoelectron spectroscopy, which may lead to the formation of antiferromagnetic Mn-rich interface regions and, hence, results in the exchange interaction between the ferromagnetic Co1−xMnx film and the antiferromagnetic Mn-rich interface region. © 1997 American Institute of Physics.
