Abstract
Epitaxial films grown by coevaporation of Co and Cu on Cu(111) were investi gated by low-energy electron diffraction and surface magneto-optical Kerr-e ffect measurements. The films are dominantly face-centered-cubic stacked up to high Co concentrations and exhibit ferromagnetism. Their coercivity is significantly reduced compared to pure Co films produced by thermal Co depo sition on Cu(111) independent of the use of Pb as a surfactant.
