Abstract

Λ-hypernuclear magnetic moments have been studied self-consistently in time-odd triaxial relativistic mean-field approach with newly proposed Λ-meson interactions. The ωΛΛ tensor coupling highly reduces the polarized Dirac magnetic moment. The deviation of the magnetic moment from the Schmidt value Δμ is related to effective nucleon-meson interaction. A large deviation Δμ with l_Λ≠0 is found to exist only in medium-mass hypernuclei.
