【 摘 要 】

We report oscillatory magnetoresistance in various superconducting films, with a magnetic-field period Delta B similar to 0.1 T that is essentially independent of sample dimensions, temperature, transport current, and the magnitude and orientation of the magnetic field, including magnetic fields oriented parallel to the film plane. The characteristics of these oscillations seem hard to reconcile with previously established mechanisms for oscillations in magnetoresistance, suggesting the possibility of another type of physical origin.
