Giant Nonvolatile Electric Field Control of Proximity‐Induced Magnetism in the Spin–Orbit Semimetal SrIrO3

“…The iridates display SOC which is on a similar energy scale than that of the electron correlation or electronic bandwidth. [ 9 ] Therefore, they are at the verge of a magnetic ground state and may display AFM or FM properties as well, depending on the details of the Hubbard interaction U and SOC. [ 9 ] The rather large Ir5 d and O2 p orbital hybridization in SrIrO 3 (SIO) ( n = ∞) results in a semimetallic paramagnetic state.…”

[ 12 ] Recent first principle calculations on SIO/LCO heterostructures indicate that it originates from unconventional topology of the electronic band‐structure of FM SIO.…”
