Abstract：
The magnetic moments of nuclei near double closed-shell with A=133, 207, 209 are calculated within spherical and triaxial deformed relativistic mean field theory. The relativistic effect and core polarization effect on nuclear magnetic moment have been examined. The observed large discrepancy between Schmidt values and experimental data for ¹³³Sb and ²⁰⁹Bi can be reduced significantly with the consideration of time-odd magnetic potential in triaxial deformed RMF theory.
