The carrier transport and the motion of a vortex system in the electron-doped high-temperature superconductors Nd${}_{2-x}$Ce_xCuO₄ in underdoped and optimally doped (x = 0.135, 0.145, 0.15) regions, in the area of the evolution from antiferromagnetic to superconducting order were investigated. To study the anisotropy of the transport properties of highly layered NdCeCuO system we have synthesized Nd${}_{2-x}$Ce_xCuO${}_{4+\delta }$/SrTiO₃ epitaxial films of three types with different orientations of the c-axis and conductive CuO₂ layers relative to the substrate. Such a set of samples allowed us to study the processes of both standard (in the CuO₂ layers) and lateral (across the CuO₂ layers) carrier transfer in the normal and the mixed states of a superconductor. In a flux-flow regime, in magnetic field $\mathbf{B},$ the dynamics of Abrikosov ($\mathbf{B}$ ∥ c-axis) and Josephson ($\mathbf{B}$ ∥ ab-plane) vortices are thoroughly investigated and analyzed which is perspective for scientific purposes and for practical applications in measurement technology.
