GHz non-reciprocal optical conductivity in hematite ($\hat{I}\pm$-${\text{Fe}}_2{\text{O}}_3$)

Peng Rao, Johannes Gröbmeyer, P. Peter Stavropoulos +5

We study the non-reciprocal properties of the iron oxide $\hat{I}\pm$-Fe${}_2$O${}_3$ (hematite) in the canted easy-plane antiferromagnetic phase, specifically in the GHz to THz frequency rang…
