dc.description.resumo	We investigate the long wavelength soft mode of antiferromagnetic (AF) multilayers near the field induced instability of the AF order. We show that in the vicinity of the surface spin flop field sHSSFd the frequency of the lowest mode is V2 /g2=asHSSF−Hd+bsHSSF−Hd2, where a and b are functions of the magnetic parameters of the multilayer and H is the external field strength. For antiferromagnetic films the first order term is zero (due to the absence of demagnetizing effects) and b=1.	pt_BR
