Abstract
We have studied the behavior of carriers near the field-induced superconductor–insulator transition for different disordered Y1−xPrxBa2Cu3O7−δ thin films. The measurement of longitudinal and Hall resistivities has been carried out in the magnetic fields. For the lower disordered film the superconducting transition appeared even at 10 T, while, the insulating behavior was observed for the higher disordered film. Also the temperature dependence and values of Hall angle cotθH are related to the disorder. We discuss the behavior of carriers on the viewpoint of the electronic state.
