Anisotropic magnetic excitations from single-chirality antiferromagnetic state in Ca-kapellasite
We present a ^{35}Cl NMR study for the spin S=1/2 perfect kagome antiferromagnet Ca-kapellasite [CaCu_{3}(OH)_{6}Cl_{2}·0.6H_{2}O] with a magnetic transition at T^{*}=7.2K. The static magnetic structure in the ground state has been determined to be a chirality-ordered Q=0 state, which is selected by...
