Magnetoresistivity and Hall effect measured in magnetic fields up to B = 9 T (B ║ c, J ║ ab) in electrondoped Nd2-xCexCuO4+d single crystal films with x = 0.14; 0.15; 0.18 and different oxygen content (δ) were studied in a temperature range of 0.4–4.2 K. The resistivity and Hall coefficient behaviors in the mixed state are discussed in the framework of flux-flow model with the inclusion of the back-flow of vortices owing to the pinning forces.
PACS: 72.15.Gd Galvanomagnetic and other magnetotransport effects; PACS: 74.25.F– Transport properties; PACS: 74.72.–h Cuprate superconductors.
Key words: magnetoresistivity, Hall effect, electron-doped superconductor.
