      abstract     = {In polarization experiments at storage rings, one of the
                      challenges is to maintain the spin-resonance condition of a
                      radio-frequency spin rotator with the spin precessions of
                      the orbiting particles. Time-dependent variations of the
                      magnetic fields of ring elements lead to unwanted variations
                      of the spin-precession frequency. We report here on a
                      solution to this problem by shielding (or masking) one of
                      the bunches stored in the ring from the high-frequency
                      fields of the spin rotator, so that the masked pilot bunch
                      acts as a comagnetometer for the other signal bunch,
                      tracking fluctuations in the ring on a time scale of about
                      one second. While the new method was developed primarily for
                      searches of electric dipole moments of charged particles, it
                      may have far-reaching implications for future spin physics
                      facilities, such as the EIC and NICA.},
