Abstract
This work presents the results of investigation of crystal structure of yttrium iron garnet films of different thickness using high-resolution X-ray diffractometry data and simulation of X-ray intensity distributions in the vicinity of the reciprocal lattice points by the Monte Carlo approach. The parameters of films column microstructure are determined and substantiated, and the model of their defective structure as systems of two types of dislocations with different directions of the Burgers vector is proposed.
