A phase transition involving a change in the structure of the domain walls separating antiferromagnetic domains with different directions of the antiferromagnetism vector should occur in an easy-axis antiferromagnet in a magnetic field stronger than the field corresponding to the spin-flip transition. This effect has been observed experimentally in the orthorhombic antiferromagnet CuCl2-2H20.
