ABSTRACT:
This disclosure relates to a bias field magnet for magnetic bubble memory devices which is formed of alternating layers of hard and soft ferrite powders which are subsequently fired together to form a magnetic structure. A particular embodiment of the present invention resides in a structure where the hard ferrite layer is encased on both its top and bottom surfaces by soft ferrite layers.
