A superconducting transition is observed in both composite thin films with a superconducting transition temperature of 1.2K and 1.0K, respectively. We have further measured the magnetoresistance at various temperatures and differential resistance dV/dI at different magnetic fields in these two composite thin films. In both samples, a much large critical magnetic field (~ 2 Tesla) is observed and this critical magnetic field shows li","authors_text":"Cayetano S.F. Cobaleda, D.
