An apparatus with a magnetron sputtering-coating chamber, source, target and substrate holder, includes a magnet arrangement for generating on a surface of the target, at least two tunnel-shaped magnetron magnetic fields in the form of closed loops that are substantially concentrically to, and spaced from each other. The surface consisting of a material with at least two elements of different weight. The distance between the substrate and target surface, the substrate radius, loci of erosion patterns in the surface and the radius and placement of the loops are all related to each other.
