Abstract
We report c-axis resistivity and longitudinal magnetoresistance measurements of superconducting Pr1.85Ce0.15CuO4 single crystals. In the temperature range 13⩽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.
