| dc.description | We investigated the anomalous peak resistivity below the onset $T_c$ in underdoped YBCO, reminiscent of that observed in 1D wires of conventional superconductors. We performed measurements of the angular dependence of resistivity $ρ(θ)$ in a magnetic field and the temperature dependence of resistivity $ρ(T)$, which exhibit a peak for $\textbf{B} \parallel$ ab-planes. This peak in $ρ(T)$ disappears for $\textbf{B} \parallel$ c-axis. The width of the corresponding maximum in $ρ(θ)$ at $θ=0^o$ ($\textbf{B} \parallel$ ab-planes) decreases with increasing c-axis component of the field ($B \sin θ$). The maximum in $ρ(θ)$ and $ρ(T)$ decreases with an increasing applied transport current. We analyzed the data using three different models of resistivity based on 2D resistor array, flux motion, and thermally activated phase-slips. Numerical calculations suggest that in a filamentary underdoped system, the phase-slip events could produce the anomalous resistivity close to $T_c$. | |
