Abstract

The magnetic-field dependencies of the longitudinal and Hall resistivity of the electron-doped compounds $N d_{2 - x} C e_{x} C u O_{4 + δ}$ in underdoped region (x=0.14) were investigated. It was established experimentally a strong magnetic field dependence of the Hall conductivity, $σ_{x y} (B) = C - b / B$ , in the region of magnetic fields corresponding to a transition from superconducting to resistive state. The observed feature can be explained with the sum of contributions of the quasiparticles and moving Abrikosov vortices into Hall effect in a mixed state of type-II superconductor.
