[en] Experiments at U. of Rochester (NSRL) and at Argonne National Lab, designed to measure the ground state nuclear magnetic moments of short-lived mirror isotopes in the sd-shell (²³Mg, T_1/2 = 11.3 s) and the f_7/2-shell (⁴³Ti, T_1/2 = 0.49 s, and ⁴⁵V, T_1/2 = 0.54 s) are presented. Reaction products are mass separated using the Rochester RMS (²³Mg) or the Argonne FMA (⁴³Ti, ⁴⁵V), polarized by passage through tilted carbon foils and implanted in a crystal host which is surrounded by an rf coil and immersed in an external magnetic holding field. Anisotropic Β-emission serves as signature of ensemble polarization, and a frequency scan of the applied rf locates the nuclear magnetic resonance when decay asymmetry vanishes. Adequate decay asymmetry has been observed for ²³Mg in cooled MgO and Pt host crystals, resulting in a few rf scans and a preliminary magnetic moment value. Sufficient production yield and separation of ⁴³Ti and ⁴⁵V have been observed, and polarization tests are currently underway. Progress for these systems as well as improvement on the ²³Mg moment will be presented
