Show affiliationsThe oscillation of a photocurrent produced by illumination of a mesoscopic metal film as a function of external magnetic field is considered. The orientation of the magnetic field B is assumed to be arbitrary. The thickness of the film is supposed to be much larger than the penetration depth of light but much smaller than the electron mean free path due to the scattering in the bulk of the sample. The oscillation of the current in the plane of light incidence is analyzed.
Our theory predicts oscillations of two types. The first type can exist for any constant energy surface, including spheres. The second type can exist only for nonspherical constant energy surfaces. The amplitudes of the oscillations of the first and second type are proportional, respectively, to B−3 and B−3/2.
