Conversion electron Mössbauer spectroscopy (CEMS) has been employed to study the magnetic moment of Fe in proximity to Pd at the interfaces of [Pd 53 Å/Fe t Å]25 multilayers grown by dc magnetron sputtering (t was varied from 5 Å to 40 Å). At room temperature, all of the multilayers were ferromagnetically ordered. Analysis gives an interface Fe layer thickness of ∼2 monolayers. The ground state hyperfine field (Bhf), extracted from the temperature dependence of Bhf, was found to be as high as 38.9 T, corresponding to a ground state Fe moment of 2.8 μB.
