Abstract
We show that spatial fluctuations of the interplane exchange coupling may produce a random large scale spin structure coexisting with orthog onally ordered magnetizations of ferromagnetic films. Despite the exis tence of long range order, spatial magnetic fluctuations are large bec ause of nonperturbative effects. An estimate of the biquadratic coupli ng between magnetic films, associated with the structure, is presented .
