Effect of Bismuth Content on the Stability of (R,Bi)3(Fe,M)5O12 (R = Ln, Y; M = Ga, Al) Garnet Solid Solutions

Published experimental data are used to assess the feasibility of adding bismuth to (R,Bi)3(Fe,M)5O12 (R = Ln, Y; M = Ga, Al) multicomponent solid solutions with the garnet structure using various synthesis techniques. We demonstrate that the existing approaches for producing (R,Bi)3(Fe,M)5O12 films and coatings are incapable of ensuring reproducibility of their chemical composition and phase stability.
