A search was made among vμ charged current events collected in the NOMAD experiment for the reaction: Vμ + N → μ- + D*- + hadrons D0+ π+ K- π+. A high purity D *+ sample composed of 35 events was extracted. The D*+ yield in Vμ charged current interactions was measured to be T = (0.79 ± 0.17(stat.) ± 0.10(syst.))%. The mean fraction of the hadronic jet energy taken by the D*+ is 0.67 ± 0.02(stat.) ± 0.02(syst.). The distributions of the fragmentation variables z, PT2 and xF for D *+ are also presented. © 2002 Elsevier Science B.V. All rights reserved.\
