Development of Garnet Films for Magnetostatic Wave Channelized Receivers

Abstract

Single Crystal films of Bi3-xLuxFe5Ol2 were grown by liquid phase epitaxy on one inch diameter wafers of GGG. Most compositions were centered about X=2.17 with dopants of Mg2+ to control the optical absorption. More than 100 experimental films were grown under a variety of growth conditions. The film properties were measured at Airtron and correlated with growth conditions. In addition, measurements of optical absorption, electrical resistivity, resonance linewidth, and Faraday rotation were performed on selected samples. Microwave passband measurements were also conducted at University of Delaware and Westinghouse Research Laboratory to determine the suitability of our films for channelizer devices. Thus far an unknown problem with these films has prevented passband measurements equivalent to pure YIG films. Garnet Films, Channelizers, Magnetostatic Waves, Liquid phase epitaxy.
