Query: Neutrino mass and magnetic moment in supersymmetry without R-parity in
  the light of recent data   We consider the generation of neutrino Majorana mass and transition magnetic
moment by the lepton-number violating $\lambda$ and/or $\lambda'$ couplings in
R-parity-violating supersymmetric models. We update (and improve) the existing
upper limits on the relevant couplings using the most recent data on neutrino
masses and mixings, indicating also the possible improvement by the GENIUS
project. We study the implication of this update on the induced neutrino
magnetic moment.
