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

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 rho(xx)(B) and the out-of-plane rho(xy)(B) resistivities in the mixed state is mainly determined by B-perpendicular to, the perpendicular to j component of B, that indicates the crucial role of the Lorentz force, F-L similar to [j x B] and defines the motion of Josephson vortices across the CuO2 layers.

The study investigates the carrier transport and vortex system motion in an electron-doped high-temperature superconductor Nd2-xCexCuO4. By synthesizing Nd2-xCexCuO4/SrTiO3 epitaxial films with non-standard orientations, the crucial role of the Lorentz force on the motion of Josephson vortices across CuO2 layers in the mixed state is revealed. The anisotropy of galvanomagnetic effects in the highly layered NdCeCuO system is mainly determined by the perpendicular component of the magnetic field relative to the current.
