摘要：

Magnetic moments of heavy charmed baryons with J(P) = 3/2(+) are predicted employing the concept of effective quark mass and screened charge of quark. We also extend our scheme to predict the 3/2(+) -> 1/2(+) transition magnetic moments. A comparison of our results with the predictions obtained in recent models is presented.
