In an apparatus for coating substrates (9), especially with magnetizable materials such as NiFe, with a circular, disk-shaped, rotatably supported substrate holder (3), which is subjected to an HF bias voltage, which is provided around its circumference and on the back with dark-space shield (1), and which rotates under at least one opposing cathode (7), and with a device for generating a magnetic field (13) parallel to the plane of the substrate (9), the magnetic field is generated by an electromagnet, the exciter coil of which, together with the lower part of the yoke (10), is housed in the dark-space shield (1), whereas the extended pole pieces (12, 12'), which are electrically insulated from the coil yoke (10) via the dark space gap (2), are housed in the substrate holder (3) in proximity to the substrate (9).
