Vortex motion in tilted magnetic fields in highly layered electron-doped superconductor Nd2-xCexCuO4

Abstract The carrier transport and the motion of a vortex system in a mixed state of an electron-doped high-temperature superconductors Nd2-xCexCuO4 were investigated. To study the anisotropy of galvanomagnetic effects of highly layered NdCeCuO system we have synthesized Nd2-xCexCuO4/SrTiO3 epitaxial films with non-standard orientations of the c-axis and conductive CuO2 layers relative to the substrate. The variation of the angle of inclination of the magnetic field, B, relative to the current, J, reveals that the behavior of both the in-plane ρ x x ( B ) and the out-plane ρ x y ( B ) resistivities in the mixed state is mainly determined by B ⊥ , the perpendicular to J component of B, that indicates the crucial role of the Lorentz force, F L ∼ [ J × B ] and defines the motion of Josephson vortices across the CuO2 layers.
