The magnetic dipole moments of the doublyheavy baryons include significant data on their inner structure and geometric shape. Moreover, understanding the electromagnetic properties of doubly-heavy baryons is the key to confinement and heavy flavor effects. Inspired by this, we extract the magnetic dipole moments of the spin- 1/2 bottom-charm baryons utilizing the QCD light-cone sum rule with considering the distribution amplitudes of the photon. The magnetic dipole moments are obtained as mu (Xi bc)+ = -0.50(-0.12)(+0.14) mu N, mu(Xi bc)0 = 0.39(-0.05)(+0.06) mu N and mu(0)(Omega bc) = 0.38(-0.04)(+0.05) mu N, mu Xi'(+)(bc) = 0.57(-0.12)(+0.13) mu(N), mu(Xi bc)'(0) = -0.29(-0.06)(+0.07) mu(N) and mu Omega(0)(bc) = -0.26(-0.05)(+0.06) mu N. Comparing the results obtained on the magnetic dipole moments of the Omega((')0)(bc) baryon with those of the Xi((')0)(bc) bc baryon, the U-symmetry is minimally broken. We have compared our results with other theoretical predictions that could be a useful complementary tool for the interpretation of the doubly-heavy baryon sector, and we observe that they are not in mutual agreement with each other.
