The QCD spectral sum rules in the presence of the external electromagnetic field F{sub {mu}{nu}} are used to calculate the magnetic moments of {Sigma}{sub c} and {Lambda}{sub c}. Our results are {mu}{sub {Sigma}{sub c}{sup ++}}=(2.1{plus_minus}0.3){mu}{sub N}, {mu}{sub {Sigma}{sub c}{sup +}}=(0.6{plus_minus}0.1){mu}{sub N}, {mu}{sub {Sigma}{sub c}{sup 0}}=({minus}1.6{plus_minus}0.2){mu}{sub N}, and {mu}{sub {Lambda}{sub c}}=(0.15{plus_minus}0.05){mu}{sub N}. {copyright} {ital 1997} {ital The American Physical Society}
