Abstract
The thermopower of a normal ring with one superconducting contact has been found to oscillate in a magnetic field with a period corresponding to the magnetic flux quantum through the area of the ring. The oscillation symmetry is the same as that of the magnetoresistance. The absolute value of thermopower is of the order of 2nV∕K. These two facts suggest that the observed thermopower is due to quasiparticle thermoelectric currents in the ring rather than the giant thermopower in the superconductor-normal loops reported earlier.
