Nernst effect and thermopower in an infinite-layer nickelate superconductor
ORAL
Abstract
The diffusion of superconducting vortices generates a Josephson electric field that can be probed in transport experiments (vortex Nernst effect). Famously, large vortex Nernst signals have been recorded in the high-Tc cuprate superconductors at temperatures well above the loss of the Meissner effect (flux expulsion) [1]. The discovery of superconductivity in the infinite-layer nickelates, (A,Sr)NiO2 (A=La, Pr, Nd) [2], has drawn many comparisons to the cuprates. We discuss careful measurements of the vortex Nernst effect and thermopower in the precursor regime of superconducting Nd1-xSrxNiO2 thin films.
