Abstract
A magnetron cathode for cathodic evaporation apparatus with a target holder (10) for releasably securing a plate-like target (9). The associated magnet arrangement (7) has pole faces (7c, 7d) for producing at least one circumferentially closed tunnel of magnetic field lines which overlaps the target. The magnet arrangement (7) is accommodated in a housing of non-ferromagnetic material which extends over the pole faces. To increase the utilization factor of the target material without the pole faces or housing parts participating in the atomization process,
