Origin of the anomalous low temperature upturn in resistivity in the electron-doped cuprates

Y. Dagan, A. Biswas, M. C. Barr +2

The temperature, doping and field dependences of the magnetoresistance (MR) in Pr_(2-x)Ce_(x)CuO_(4-delta) films are reported. We distinguish between orbital MR, found when the mag…
