In this work, we investigate the chiral corrections to the magnetic moments of the spin- 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:

. As a by-product, we have also calculated the magnetic moments of the spin-
doubly bottom baryons and charmed bottom baryons:
