We have investigated fcc FexCo1-x/Cu(1 0 0) alloy films with linear magnetic dichroism in photoemission. Specifically we studied the emission from the Fe 3p core level. For the first time, we have observed fine structure for linear dichroism in the photoelectron emission of the Fe 3p core level and confirmed our assignments using spin-polarized photoelectron spectroscopy. This conclusively demonstrates the validity of the single electron, density of states model for the 3p manifold of 3d magnetic materials.
