Successive magnetic phase transitions in $\mathbf{\alpha }$-RuCl${}_3$: XY-like frustrated magnet on the honeycomb lattice

Yumi Kubota, Hidekazu Tanaka, Toshio Ono +2

The layered compound $\alpha$-RuCl${}_3$ is composed of a honeycomb lattice of magnetic Ru${}^{3+}$ ions with the $4d^5$ electronic state. We have investigated the magnetic properties of $α…
