In this work, we investigate the chiral corrections to the magnetic moments of the spin- $$3\over 2$$ 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: $$\mu _{\varXi ^{*++}_{cc}}=2.61\mu _{N}$$ , $$\mu _{\varXi ^{*+}_{cc}}=-0.18\mu _{N}$$ , $$\mu _{\varOmega ^{*+}_{cc}}=0.17\mu _{N}$$ . As a by-product, we have also calculated the magnetic moments of the spin- $$3\over 2$$ doubly bottom baryons and charmed bottom baryons: $$\mu _{\varXi ^{*0}_{bb}}=2.83\mu _{N}$$ , $$\mu _{\varXi ^{*-}_{bb}}=-1.33\mu _{N}$$ , $$\mu _{\varOmega ^{*-}_{bb}}=-1.54\mu _{N}$$ , $$\mu _{\varXi ^{*+}_{bc}}=3.22\mu _{N}$$ , $$\mu _{\varXi ^{*0}_{bc}}=-0.84\mu _{N}$$ , $$\mu _{\varOmega ^{*0}_{bc}}=-1.09\mu _{N}$$ .
