W. Yu, B. Liang, and R. L. Greene
TL;DR
This study investigates the c-axis resistivity and magnetoresistance of Pr1.85Ce0.15CuO4 single crystals, revealing superconducting fluctuation effects and unexplained low-temperature behaviors.
Contribution
It provides new experimental data on magnetoresistance in electron-doped cuprates and links negative magnetoresistance to superconducting fluctuations.
Findings
Negative magnetoresistance observed above Hc2 between 13K and 32K.
Superconducting fluctuations likely cause the negative magnetoresistance.
Unexplained resistivity upturn occurs below 13K.
Abstract
We report c-axis resistivity and longitudinal magnetoresistance measurements of superconducting Pr1.85Ce0.15CuO4 single crystals. In the temperature range 13K<T<32K, a negative magnetoresistance is observed at fields just above Hc2. Our studies suggest that this negative magnetoresistance is caused by superconducting fluctuations. At lower temperatures (T<13K), a different magnetoresistance behavior and a resistivity upturn are observed, whose origin is still unknown.
