A visual polarization method was used to observe and investigate the magnetic intermediate state produced in dysprosium orthoferrite in a magnetic field when the crystal goes over from the antiferromagnetic state (Gy) into the weakly ferromagnetic state (GXFZ). The region of the existence of the intermediate state is outlined in the (HT) plane. The dependences of the phase concentrations and of the domain dimensions on the magnetic field intensity are determined. It is shown that the observed domain structure of the magnetic ordered state is close to thermodynamic equilibrium.
