      abstract     = {We predict that a single-level quantum dot without
                      discernible splitting of its spin states develops a
                      spin-precession resonance in charge transport when embedded
                      into a spin valve. The resonance occurs in the generic
                      situation of Coulomb blockaded transport with ferromagnetic
                      leads whose polarizations deviate from perfect antiparallel
                      alignment. The resonance appears when electrically tuning
                      the interaction-induced exchange field perpendicular to one
                      of the polarizations—a simple condition relying on vectors
                      in contrast to usual resonance conditions associated with
                      energy splittings. The spin resonance can be detected by
                      stationary dI/dV spectroscopy and by oscillations in the
                      time-averaged current using a gate-pulsing scheme. The
                      generic noncollinearity of the ferromagnets and junction
                      asymmetry allow for an all-electric determination of the
                      spin-injection asymmetry, the anisotropy of spin relaxation,
                      and the magnitude of the exchange field. We also investigate
                      the impact of a nearby superconductor on the resonance
                      position. Our simplistic model turns out to be generic for a
                      broad class of coherent few-level quantum systems.},
