ABSTRACT:
The liquid phase epitaxial growth of a magnetic garnet film is obtained by providing a circulating flux solution of the material, wherein spaced apart zones are maintained at different temperatures, above and below the saturation point; and by placing a preheated substrate in contact with the supersaturated zone, wherein a suitable growth temperature is maintained. This system avoids the prior need for heating and cooling the entire solution as a single, thermally uniform zone, and thereby achieves a substantial savings in time which permits at least a ten-fold increase in production rates, without increasing manpower or capital investment.
