EVIDENCE FOR QUANTIZED VORTICES IN A SUPERCONDUCTING STRIP
Results of a study of the properties of extremely narrow superconducting film strips in a perpendicular magnetic field are reported. Resistivity vs magnetic field curves obtained in the intermediate state at the transition temperature indicate that quantized current vortices are present, and that in the limit of very narrow strips, their size depends upon the width of the strip.
