We calculate the magnetic moments of heavy baryons with a single heavy quark in the bound-state approach. In this approach the heavy baryons is considered as a heavy meson bound in the field of a light baryon. The light baryon field is represented as a soliton excitation of the light pseudoscalar and vector meson fields. For these calculations we adopt a model that is both chirally invariant and consistent with the heavy quark spin symmetry. We gauge the model action with respect to photon field in order to extract the electromagnetic current operator and obtain the magnetic moments by computing pertinent matrix elements of this operator between the bound state wavefunctions. We compare our predictions for the magnetic moments with results of alternative approaches for the description of heavy baryon properties.

Electromagnetic polarizabilities of the spin-$\frac{1}{2}$ singly heavy baryons in heavy baryon chiral perturbation theory
At O(p^3) in heavy baryon chiral perturbation theory, sextet heavy baryons acquire polarizabilities from pion/kaon loops and from B6* to B6 magnetic transitions, while antitriplet heavy baryons have zero polarizability.

Electromagnetic form factors of singly charmed baryons $\Sigma_c$ and $\Lambda_c$ in a covariant quark-diquark model
Spacelike electromagnetic form factors of Σc and Λc are computed in a covariant quark-diquark model, finding compact charge distributions and a charm-quark-dominated magnetic form factor for Λc.
