Abstract

Ultrathin ferromagnetic Fe films have been grown on an Au(OOl) surface. Using the angular profile measurements of High-Resolution LEED (HRLEED), we show the inho-mogeneities at the interface due to atomic place exchange between Fe and Au atoms can drastically change the angular intensity distributions of diffraction beams. The contributions from the inhomogeneities on the surface can be properly decoupled from the total angular intensity distributions. Through the energy dependent angular profile analysis of diffraction beams, we have quantitatively determined the degree of inhomogeneous atomic intermixing at elevated annealing temperatures.
