Popis: We have used plots of the Auger amplitudes versus deposition time to investigate the growth mode of 3d-transition metals on noble metal (100) surfaces. The systems considered are Fe/Cu(100), Fe/Au(100), Co/Cu(100), and Cr/Ag(100). We find that: 1. The Auger plots consist of a succession of straight lines of constant length with sharp breaks in between, i.e. the growth mode is essentially layer-by-layer. 2. From the experimental data points a slight rounding off in the vicinity of the break points cannot be excluded, although a numerical analysis shows that the deviation from perfect layer-by-layer growth is less than 10% of a monolayer for all systems considered.
