Abstract： We investigate the effect of intrinsic sea quark-antiquark pairs on the magnetic moments of the SU(3) octet baryons. The intrinsic quark-antiquark pairs are introduced by a model of energetically-favoured non-perturbative baryon-meson fluctuations. It is shown that the baryon-meson fluctuation model provides a mechanism of SU(3) symmetry breaking in the baryon sea and is related to the violations of Gell-Mann-Okubo and Coleman-Glashow sum rules for the baryon magnetic moments. Such a model is also consistent with its explanation of the violations of Gottfried and Ellis-Jaffe sum rules in deep inelastic scattering.
