Abstract
The equations of spin dynamics of a normal Fermi liquid in a nonuniform magnetic field have a special symmetry. Because of this symmetry the equations have steady-state solutions which describe coherently precessing structures. The structures consist of two domains. In one of the domains the magnetization is parallel and in the other it is antiparallel to the magnetic field. Within the domain wall the magnetization can rotate by any odd multiple of π. The possibility of realization of analogous structures in the other physical systems is discussed.
