| Abstract: | The effect of an external magnetic field on the characteristics of domain walls was studied in a four-sublattice antiferromagnet
La2CuO4. It was shown that a transition of domain-wall structure from one type into other types is possible for certain values of
the fields. The critical fields of the transition were determined. The phase diagram of the stability of different types of
domain walls was constructed.
