Abstract	We report muon spin rotation measurements on the S=1/2 (Cu2+) paratacamite ZnxCu4-x(OH)6Cl2 family. Despite a Weiss temperature of ~ -300 K, the x = 1 compound is found to have no transition to a magnetic frozen state down to 50 mK as theoretically expected for the kagome Heisenberg antiferromagnet. We find that the limit between a dynamical and a partly frozen ground state occurs around x = 0.5. For x = 1, we discuss the relevance to a singlet picture.
