Electric and magnetic field control of superconducting transition at the LaAlO$_{3}$/SrTiO$_{3}$ heterointerface

ORAL

Abstract

We report on detailed measurements of the normal state-superconducting phase transition of the two-dimensional electron gas that develops at the LAO/STO interface as a function of gate voltage and magnetic field. We will discuss the specifics of the R versus T and the T-H phase diagrams for this superconductor and the potential origin of observed dissipation and hysteretic behavior. These data are analyzed in connection with magnetoresistance and Hall measurements.
