The mixed-state Hall conductivity of single-crystal films $N{d}_{2-x}C{e}_{x}Cu{O}_{4+\delta }$ (x=0.14)

Abstract

The magnetic-field dependencies of the longitudinal and Hall resistivity of the electron-doped compounds $N{d}_{2-x}C{e}_{x}Cu{O}_{4+\delta }$ in underdoped region (x=0.14) were investigated. It was established experimentally a strong magnetic field dependence of the Hall conductivity, ${\sigma }_{xy}(B)=C-b/B$, 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.
