Atomically controllable insulator-to-metal transition in strongly correlated insulator iridate/manganate heterostructures

"conductive interface of 2 correlated insulators has rich phase diagram even covering insulating/ metallic states by itself... dirac semimetal 5d iridate CaIrO3, robust half-metal manganite La0.67Sr0.33MnO3 heterostructure... layered deposition with varying thicknesses of CIO and LSMO... under tensile strain, both metals stabilized into insulating states, electrical properties varied depending on CIO layer thickness... high saturation field >30 Tesla at 20 K... formed conductive path when subjected to high magnetic field"
