The electromagnetic properties of the baryon octet are calculated in quenchedQCD on a 20^3 x 40 lattice with a lattice spacing of 0.128 fm using thefat-link irrelevant clover (FLIC) fermion action. FLIC fermions enablesimulations to be performed efficiently at quark masses as low as 300 MeV. Bycombining FLIC fermions with an improved-conserved vector current, we ensurethat discretisation errors occur only at O(a^2) while maintaining currentconservation. Magnetic moments and electric and magnetic radii are extractedfrom the electric and magnetic form factors for each individual quark sector.  From these, the corresponding baryon properties are constructed. Our resultsare compared extensively with the predictions of quenched chiral perturbationtheory. We detect substantial curvature and environment sensitivity of thequark contributions to electric charge radii and magnetic moments in the lowquark mass region. Furthermore, our quenched QCD simulation results are inaccord with the leading non-analytic behaviour of quenched chiral perturbationtheory, suggesting that the sum of higher-order terms makes only a smallcontribution to chiral curvature.Comment: 29 pages, 33 figures, 20 table
