Abstract
Core-polarisation and meson-exchange current calculations have been perform ed at Sr-88 and Zr-90 closed-shell cores to determine the effective magneti c dipole operator for valence orbitals. The values obtained show considerab le core- and orbit-dependency. The results are tested in shell-model calcul ations for magnetic moments in N=50 and N=51 nuclides and the comparison wi th experiment is satisfactory.
