Abstract
The dependence of the energy γ180 and the halfwidth δ180 of 180° L‐domain walls in antiferromagnets on the magnetic field H is calculated for low fields. At H → H0 (H0 is the critical field of the spin‐flop transition) the walls expand and their energy γ180 decreases. In the spin‐flop region 90° domain structure appears. γ90 and δ90 are determined by the value of fourth‐order anisotropy constant K2. The calculation of the metastable state (K2 0 are discussed. The problem of the new magnetic phase nucleation is considered.Keywords
