The first observation of spin-dependent photoelectron diffraction using circularly polarized x rays is reported for monolayer ferromagnetic fcc Fe films on Cu(001). Circularly polarized x rays are used to produce spin-polarized photoelectrons from the Fe2[ital p] spin-orbit split doublet, and intensity asymmetries in the 2[ital p]3/2 level of [approx]3% are observed. The asymmetry is dependent on the relative orientation of the x-ray polarization vector and the Fe magnetic moment. This spin-dependent technique promises the direct, element-specific determination not only of local atomic structure, but magnetic structure as well.
