Single-crystal magneto-uniaxial films of the garnet Y3-xB^xFe5-yAV^12 were Srown by a liquid epitaxy method. The Faraday rotation, the optic extinction coefficient, the magnetic characteristics of the films, and the domain-structure parameters were measured at wavelengths 0.5 1.0 μ. The obtained material was found to have a unprecedented large optical Q factor and a stable cylindrical magnetic domain structure.
