Abstract
Angle-resolved photoemission from thin films of Ag on Fe(100) grown with a low temperature deposition and annealing technique shows clear quantum well peaks for coverages up to 12 monolayers. Pairs of peaks are sometimes observed in the spectra; atomic layer resolution is demonstrated and used to explain these pairs without invoking spin splitting. The peaks are observed only within an energy window defined by the minority spin hybridization gap within the Fe substrate. Large intensity variations of the quantum well states with photon energy are observed.
