Abstract
Dynamics of domain walls in four-sublattice La2CuO4-type antiferromagn ets in external magnetic field is investigated. In the linear in field amplitude approximation, the oscillating field is shown to induce vib rations of acoustic type walls. In the second order of the perturbatio n-theory it is proposed that there is a drift motion of such domain wa lls. The drift velocity is calculated and its dependences on field fre quency and polarization are analyzed.
