Abstract
The authors have measured the resistive transition broadening of granular polycrystalline YBa2Cu3Ox thin films as a function of the magnetic field in the temperature range below 90 K and magnetic fields of up to 20 T. The experimental results show that the broadening of resistive transition with increasing magnetic field strength is consistent in many respects with Tinkham's model based on the concept of giant flux creep.
