An intermediate state revealed upon a first-order metamagnetic phase transition in a magnetic field aligned parallel to the Ising c axis of Er3+ ions in crystals of erbium ferrite ErFeO3 at a temperature of 1.6 K is visualized for the first time. The region of existence of the intermediate state and the parameters of the domain structure are determined, and the possible conditions providing for visualization of the intermediate state and its specific features are analyzed. A thermodynamic model is proposed for the stabilization of the intermediate state. It is shown that theoretical results are in good agreement with experimental data.
