Abstract

We report AC susceptibility and resistivity measurements of the vortex motion in single crystal YBa_2Cu_3O_(7−δ), with δ ~ 0.62. The superconducting transition temperature was varied from 7 K to 17 K by altering the oxygen vacancy ordering in the chains. We find that both the slope of the irreversibility line and its extrapolated zero temperature value scale linearly with T_c, providing strong evidence for the intrinsic nature of the irreversibility line. Moreover, the reduced magnetic field scale of oxygen deficient crystals allows us to obtain new results at previously inaccessible reduced temperatures, well below T_c.
