On domain structure in rare-earth ferrite garnets

Calculated in the paper is a domain structure in rare-earth ferrite-garnets. Field and temperature dependence of energy and domain wall thickness have been obtained. In case the external field is perpendicular to the easy magnetization axis the domain structure proves to be typical of the whole range of the angular phase. In case the field runs parallel to the easy magnetization axis there is a range of domain structure in the fields exceeding 4π Ms along with the classical region. Analytical dependences of domain size upon the field and temperature are presented
