We perform a relativistic chiral effective-field theory calculation of the radiative pion photoproduction (gammap--> pi(0)pgamma(')) in the Delta-resonance region, to next-to-leading order in the "delta expansion." This work is aimed at a model-independent extraction of the Delta(+) magnetic moment from new precise measurements of this reaction. It also predicts the chiral behavior of Delta's magnetic moment, which can be used to extrapolate the recent lattice QCD results to the physical point.
