Abstract [en]

We suggest to modify the usual iron garnet sensor film for magneto-optical imaging by introducing a Bragg mirror consisting of heteroepitaxial garnet layers between the substrate and sensor film. For the example situation of a hexagonal vortex lattice in a type II superconductor, we show by calculation that the quality factors of image contrast and optical efficiency can be higher for the proposed heteroepitaxial garnet multilayers than for the single-layer garnet films currently in use as sensor films.
