摘要：
In this work, we investigate the chiral corrections to the magnetic moments of the spin-3/2 doubly charmed baryons systematically up to next-to-next-to-leading order with the heavy baryon chiral perturbation theory. The numerical results are given up to next-to-leading order: mu(Xi cc)*(++) = 2.61 mu(N), mu(Xi cc)*(+) = -0.18 mu(N), mu(Omega cc)*(+) = 0.17 mu(N). As a by-product, we have also calculated the magnetic moments of the spin-3/2 doubly bottom baryons and charmed bottom baryons: mu(Xi bb)*(0) = 2.83 mu(N), mu(Xi bb)*(-) = -1.33 mu(N), mu(Omega bb)*(-) = -1.54 mu(N), mu(Xi bc)*(+) = 3.22 mu(N), mu(Xi bc)*(0) = -0.84 mu(N), mu(Omega bc)*(0) = -1.09 mu(N).
