Nonreciprocal directional dichroism in rare-earth excitations of chiral Er-containing oxides

ORAL

Abstract

Telecommunications utilize complex oxides and chiral materials in magneto-optical devices, such as isolators and circulators, to help control the transmission of data. Nonreciprocal directional dichroism is an optical magnetoelectric effect that arises in materials that possess strong spin-orbit coupling as well as broken inversion and time reversal symmetries. Our work discusses nonreciprocity in chiral, Er-containing oxides for potential applications in magneto-optical devices.
