Abstract(s)Multilayer thin films consisting of alternate layers of metal and oxide have been prepared by magnetron sputtering. The films have been studied by optical and photoacoustic spectroscopy (PAS) and thicknesses determined from the interference patterns. The non-destructive PAS technique gives reliable results for dielectric layers thicker than about 100 nm.
