Ab Initio Cycloidal and Chiral Magnetoelectric Responses in Cr${}_2$O${}_3$

Natalie Tillack, Jonathan R Yates, Paolo G Radaelli

We present a thorough density functional theory study of the magneto-electric (ME) effect in Cr${}_2$O${}_3$. The spin-lattice ME tensor $\alpha$ was determined in the low-field and spi…
