A technique to produce spin orientation in RI beams was developed for measurements of nuclear moments. The present scheme of two-step reaction realized highly spin-aligned RI beams for a wide range of exotic nuclei. Recently the two-step reaction scheme was applied to the magnetic moment measurement of an isomeric state of a neutron-rich nucleus ~(75)Cu, where its magnetic moment was determined for the first time owing to a 30%-spin-aligned beam. A further perspective of the nuclear moment measurements employing the present scheme is expected.
