X-ray investigations of structure of thick YIG epitaxial systems of different growth parameters

Abstract

Crystal and magnetic domain structures of iron garnet films with different thicknesses are studied by means of atomic and magnetic force scanning microscopies as well as by means of high-resolution Х-ray diffraction. The model of the garnet films as a set of vertical columns with certain lateral sizes is proposed and substantiated. Within this model, X-ray intensity distributions in the vicinity of the reciprocal lattice points are calculated using the Monte Carlo approach to determine densities of two dislocation types with different Burgers vectors.
