We report a significantly enhanced photon drag effect (PDE) in a Au thin film at the surface plasmon resonance when the film is mounted in the Kretschmann-Raether geometry. The PDE is observed in the form of an electrical direct current induced by optical excitation. We discuss a model to describe how excitation of surface plasmons may give rise to a current in the Au thin film.
