      abstract     = {This paper reports the first simultaneous measurement of
                      the horizontal and vertical components of the polarization
                      vector in a storage ring under the influence of a radio
                      frequency (rf) solenoid. The experiments were performed at
                      the Cooler Synchrotron COSY in Jülich using a vector
                      polarized, bunched 0.97  GeV/c deuteron beam. Using the
                      new spin feedback system, we set the initial phase
                      difference between the solenoid field and the precession of
                      the polarization vector to a predefined value. The feedback
                      system was then switched off, allowing the phase difference
                      to change over time, and the solenoid was switched on to
                      rotate the polarization vector. We observed an oscillation
                      of the vertical polarization component and the phase
                      difference. The oscillations can be described using an
                      analytical model. The results of this experiment also apply
                      to other rf devices with horizontal magnetic fields, such as
                      Wien filters. The precise manipulation of particle spins in
                      storage rings is a prerequisite for measuring the electric
                      dipole moment (EDM) of charged particles.},
