Low Energy Dynamics in Spin-Liquid and Ordered Phases of S=1/2 Antiferromagnet Cs sub(2)CuCl sub(4)

Cs sub(2)CuCl sub(4) realizes spin-1/2 quantum antiferromagnet on a distorted triangular lattice. It remains in a quantum spin-liquid state far below Curie-Weiss temperature 4 K and exhibits an incommensurate spin ordering at T sub(N)0.6 K. We studied Cs sub(2)CuCl sub(4) by means of electron spin r...

Description
Summary:Cs sub(2)CuCl sub(4) realizes spin-1/2 quantum antiferromagnet on a distorted triangular lattice. It remains in a quantum spin-liquid state far below Curie-Weiss temperature 4 K and exhibits an incommensurate spin ordering at T sub(N)0.6 K. We studied Cs sub(2)CuCl sub(4) by means of electron spin resonance (ESR) at temperatures down to 0.05 K in the frequency range 9
