Impact of spin-density-wave order on thermal transport in the cuprate superconductor LSCO

ORAL

Abstract

We report low temperature thermal conductivity measurements in the cuprate superconductor LSCO for samples with a doping x between 0.125 and 0.15. In this doping range, spin-density-wave order coexisting with superconductivity can be induced by applying a magnetic field [1,2]. We study the impact of this order on the conduction of d-wave quasiparticles by measuring the residual thermal conductivity κ0/T in the T → 0 limit, as a function of doping and magnetic field.
