Abstract

The local magnetic structure of TbFe multilayers with various layer thicknesses of Tb (26 Å) and Fe (10, 20, 30 and 35 Å) has been investigated by circular magnetic x-ray dichroism (CMXD) studies. From the dichroic signal at the L₃ edge both the local magnetic Tb moment and the anisotropic behavior of the Tb compound could be deduced. The magnetic spectra at the Tb L₂ edge and the Fe K edge, which are known to be sensitive to the local chemical environment, have been used to obtain information on the binding characters of the magnetized atoms in the various TbFe compositions. Significant deviations of the CMXD spectra compared to the corresponding spectra in the pure Fe and Tb metals have been observed. This indicates significant contributions to the magnetism from an interface region, whose chemical structure resembles strongly those of the intermetallic TbFe ₂ compounds.
