First-principles study of KCoF${}_3$: Jahn-Teller effect, dynamical magnetic charges, magnetoelectric multipoles and antimagnetoelectricity

Bogdan Guster, Maxime Braun, Eric Bousquet

We study from \textit{ab~initio} density functional theory calculations the structural and magnetic properties of the crystal KCoF${}_3$. We found that the experimentally reported cu…
