Spin Density Wave versus Fractional Magnetization Plateau in a Triangular Antiferromagnet

L. Facheris, K. Yu. Povarov, S. D. Nabi +7

We report an excellent realization of the highly non-classical incommensurate spin-density wave (SDW) state in the quantum frustrated antiferromagnetic insulator Cs${}_2$CoBr${}_4$. In…
