We present an experimental study of electron phase memory effects in disordered mesoscopic rings of a normal metal (Ag) with superconducting boundaries. Magneto resistance oscillations of two periods, h/2e and h/4e, were observed. The measurement current, and the position of the superconducting "mir
Transitions between fluxoid states in asymmetric mesoscopic superconducting rings are investigated experimentally. We detected the fluxoid state transitions by the voltage change across current-biased small tunnel junctions attached to the ring. We found that the temperature above which the hysteres
