Abstract

Ferroelectricity superconductivity and ferromagnetism are orders which rarely coexist due to their different symmetry and orbital requirements. A possible avenue for combining these orders is by interface design, where orders formed at the constituent materials can overlap and interact through emergent conducting electrons. In my talk I will describe our struggle to combine these orders at a conducting oxide interface. We combined transport and scanning SQUID imaging of the current flow to study and understand ferroelectric-superconductor 1 and ferroelectric-magnetic 2 heterostructures. I will also show our recent preliminary results on a magnetic-superconductor new interface where we believe that a magnetoelectric coupling can be realized.
