Abstract: The first nontrivial chiral corrections to the magnetic moments of triplet (T) and sextet (S(*)) heavy baryons are calculated using heavy hadron chiral perturbation theory. Since magnetic moments of the T hadrons vanish in the limit of infinite heavy quark mass (mQ→∞), these corrections occur at order O(1/(mQΛχ2)) for T baryons, while for S(*) baryons they are of order O(1/Λχ2). The renormalization of the chiral loops is discussed, and relations among the magnetic moments of different hadrons are provided. Previous results for T baryons are revised.
