Abstract
197Au Mössbauer spectra from teh Au/TM (TM = Fe, Co, Ni) multilayers consist mainly of two components. One component shows large hyperfine magnetic field due to the hybridization at interface between Au and TM ferromagnetic layers. The largest magnitudes of the hyperfine magnetic fields at the 197Au nuclei are close to the value at 197Au nucleus in the ferromagnetic TM metals. Another component is a nonmagnetic one arising from the middle part of the Au layers. From the area ratio of magnetic components in each spectra, the Au atoms within 0.4 nm Au layer have been perturbed by the Fe and Ni layers, and Co layers perturb 0.3 nm Au layers at the interface.
