Probing momentum-dependent scattering in uniaxially stressed Sr${}_2$RuO${}_4$ through the Hall effect

Po-Ya Yang, Hilary M. L. Noad, Mark E. Barber +4

Under in-plane uniaxial stress, the largest Fermi surface sheet of the correlated metal Sr${}_2$RuO${}_4$ undergoes a Lifshitz transition from an electron-like to an open geometry. We…
