The effect of V2O5 on the growth and properties of Bi-YIG
The effect of V2O5 additions to PbO-Bi2O3 flux was investigated with respect to the properties of Bi-YIG epitaxial films for magnetic bubble devices. The Bi content of the films (including an estimated 10 percent Pt(2+) were calculated from Faraday rotation measurements. For films grown at constant supercooling, the Bi content increased by 60 percent as the V2O5 content of the flux was increased from 0 to 9 mol pct. Lattice constant data were shown to agree with measured Bi and Ca-Si contents. The growth-induced magnetic anisotropy increased proportionally to the Bi content and could be fairly represented by a model; however, the coefficients of the model vary widely between data sets for different melt compositions.
