ABSTRACT:
The temperature variation of the bubble collapse field of a class of garnet magnetic bubble layer materials is selected by selection of the ratio PbO to B.sub.2 O.sub.3 in the flux from which the layer is grown. This permits the growth of layers, whose temperature dependence of critical magnetic properties more closely match the temperature dependence of bias magnet materials, resulting in extended operating temperature range and/or wider operating margins (with attendant improvement in manufacturing yield). Layer growth at higher ratios of PbO to B.sub.2 O.sub.3 produces films of higher rate of change of bubble collapse field with temperature.
