Growth and characterization of thin (210)-oriented epitaxial garnet films with Bi and Pr substitutions are reported. The interesting property of these films is the existence of an easy plane of magnetization inclined with respect to the film plane. This property allows for the development of high sensitivity magneto-optic imagers and indicators capable of real time detection of two-dimensional magnetic field patterns. Tailoring of the anisotropy coefficients to achieve the easy magnetization plane and its robustness are discussed. The results of experimental studies of the dependence of the anisotropy properties on the melt composition and growth conditions are reported.
