The influence of the domain structure on the magnetization processes in thin magnetic discs with uniaxial anisotropy is investigated. The critical magnetic fields of transformation from multi-domain to one-domain structure in the sample are calculated. The theoretical results are verified experimentally by the torque moment measurements.
