title: Spin-motive force due to a gyrating magnetic vortex.
abstract: A change of magnetic flux through a circuit induces an electromotive force. By                 analogy, a recently predicted force that results from the motion of non-uniform spin                 structures has been termed the spin-motive force. Although recent experiments seem                 to confirm its presence, a direct signature of the spin-motive force has remained                 elusive. Here we report the observation of a real-time spin-motive force produced by                 the gyration of a magnetic vortex core. We find a good agreement between the                 experimental results, theory and micromagnetic simulations, which taken as a whole                 provide strong evidence in favour of a spin-motive force.
