Normal-state anisotropic resistivity of ${\mathrm{Nd}}_{2\mathrm{-}\mathrm{x}}$${\mathrm{Ce}}_{\mathrm{x}}$${\mathrm{CuO}}_{4\mathrm{-}\mathrm{y}}$: Evidence for scattering by anisotropic spin fluctuations

We report measurements of the anisotropic resistivity of the electron-doped copper oxide compound ${\mathrm{Nd}}_{2\mathrm{-}\mathrm{x}}$ ${\mathrm{Ce}}_{\mathrm{x}}$ ${\mathrm{CuO}}_{4\mathrm{-}\mathrm{y}}$ using the Montgomery method. The full temperature dependence of both resistivity components is well described using a simple Boltzmann transport analysis. Deduced values of the Fermi wave vector, ${\mathrm{k}}_{\mathrm{F}}$≈0.2/a, an effective interplanar coupling, ${\mathrm{J}}_{\mathrm{\perp }}$≈39 K, the effective mass ratio, ${\mathrm{m}}_{\mathrm{c}}$/${\mathrm{m}}_{\mathrm{a}}$≈600, and the relevant electron-magnon matrix element, |${\mathrm{g}}_0^{\prime }$|≈180 meV, are reported.
