Abstract <p>A theoretical and experimental investigations are performed for regions of the coherent quasi-stationary remagnetization of ferrite–garnet films with planar anisotropy under the influence of an external magnetic field rotating in the plane of each film. The films are found to have biaxial and uniaxial anisotropy that coincide with their axes of easy magnetization. It is established that the films contain regions of the coherent and incoherent remagnetization through the nucleation and germination of a wedge-shaped domain structure. A theory is proposed that agrees with the experimental results.</p>
