  It is well known, that R-parity violating supersymmetric models predict a
non-zero magnetic moment for neutrinos. In this work we study the Majorana
neutrino transition magnetic moments within an RpV modified minimal
supergravity model. Specifically, we discuss the contributions coming from the
charged Higgs bosons, higgsinos, leptons, sleptons, charged gauge bosons, and
charginos. We use the experimental results from the MUNU collaboration to
restrict the model's parameter space. A comparison with two other types of
contributions (only trilinear RpV couplings and trilinear plus
neutrino--neutralino mixing) is also presented. We have found that the
presently discussed processes dominate significantly, exceeding in some cases
even the experimental limits.
