A magnetic head for a magneto-optical device comprises a plurality of substantially parallel planar layers, including at least one layer comprising a coil formed by a plurality of turns an electrically conductive winding, the turns lying substantially in a plane defined by the layer and the winding being substantially centered on a central axis perpendicular to the plane, and further including a yoke layer comprised of an anisotropic flux guiding material. The yoke layer comprises a plurality of segments ( 16 ) of flux guiding material dividing the yoke layer into sectors that together surround the central axis. In each sector, the flux guiding material has an easy axis in a plane of the yoke layer with a direction different from the direction of the easy axis in an adjacent sector.
