Abstract
The anomalous magnetotransport properties in electron doped (n-type) cuprates were investigated using Hall measurements at THz frequencies. The complex Hall angle was measured in overdoped Pr2−xCexCuO4 samples (x=0.17 and 0.18) as a continuous function of temperature above Tc at excitation energies 5.24 and 10.5 meV. The results, extrapolated to low temperatures, show that inelastic scattering introduces electronlike contributions to the Hall response. First-principle calculations of the Hall angle that include current-vertex corrections (CVC) induced by electron interactions mediated by magnetic fluctuations in the Hall conductivity reproduce the temperature, frequency, and doping dependence of the experimental data. These results show that Fermi-liquid CVC effects are the source of the anomalous Hall transport properties in overdoped n-type cuprates.
