Vortex motion in tilted magnetic fields in highly layered electron-doped superconductor Nd2-x Ce x CuO4

Highlights: • The carrier transport and the motion of a vortex system in HTSC NCCO mixed state. • Nd_2-xCe_xCuO₄/SrTiO₃ epitaxial films with non-standard orientations of the c-axis. • Variation of magnetic field (B) inclination angle relative to the current (j). • B perpendicular to j component defines Josephson vortices motion across CuO₂ layers. The carrier transport and the motion of a vortex system in a mixed state of an electron-doped high-temperature superconductors Nd_2-xCe_xCuO₄ were investigated. To study the anisotropy of galvanomagnetic effects of highly layered NdCeCuO system we have synthesized Nd_2-xCe_xCuO₄/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 ${\rho }_{xx}\left(B\right)$ and the out-of-plane ${\rho }_{xy}\left(B\right)$ resistivities in the mixed state is mainly determined by $B_{\perp }$, the perpendicular to j component of B, that indicates the crucial role of the Lorentz force, $F_L\sim [j\times B$] and defines the motion of Josephson vortices across the CuO₂ layers.
