Magnetic Phase Transition and Magnetization Plateau in Cs${}_2$CuBr${}_4$

H. Tanaka, T. Ono, H. A. Katori +3

The crystal structure of Cs${}_2$CuBr${}_4$ is the same as that of Cs${}_2$CuCl${}_4$, which has been characterized as a spin-1/2 quasi-two-dimensional frustrated system. The magnetic prop…
