Підтримка:The research was carried within the state assignment of
theme «Electron» (No. 01201463326), supported in part by
the Program of fundamental research of the Ural Division of
Russian Academy of Sciences (RAS) «Quantum macrophysics
and nonlinear dynamics» (project N. 15-8-2-6) with
partial support of RFBR (grant No. 15-02-02270).
The magnetic-field dependencies of the longitudinal and Hall resistivity of the electron-doped compounds Nd₂–xCexCuO₄₊δ in underdoped region (x = 0.14) were investigated. It was established experimentally a strong magnetic field dependence of the Hall conductivity, σxy(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.
