Abstract
New measurements of the dc resistivity rho(TH) of YBa2Cu3O7-x (YBCO) b elow 20K and in magnetic fields >100T (>1 Megagauss) show H(c2) parall el-to c-axis is near 140T at low temperature. The onset of hydrodynami c vortex flow is also clearly seen and is in agreement with existing d ata. We have employed a linear fit of sample voltage vs. dB/dt at low fields to systematically remove inductive coupling from the signal vol tage and extract rho(T,H).
