✦ Synopsis

Electrical resistivity of Yl_xPr:~Ba2Cu309with x=0.45 has been measured around the superconducting transition temperature in applied magnetic fields. The superconducting transition becomes once broad above 1T and then narrowing of the transition appears in higher magnetic field above 9T for HIIc-axis. Furthermore, the pinning energy U0 of the vortex which is estimated from the temperature dependence of the resistivity in the low resistivity region of the transition behaves differently with respect to the magnetic field above and below 1T. These phenomena are discussed based on the temperature dependence of the depinning field, He2 and on pinning by the twin boundary.
