摘要：

Volborthite Cu3V2O7(OH)(2) center dot 2H(2)O is a natural frustrated antiferromagnet with a kagome-like magnetic lattice decorated by S = 1/2 spins. Our mu SR results confirm the existence of a dynamical plateau below 2K, as initially demonstrated in [Phys. Rev. Lett. 91 (2003) 207603] despite sensible quantitative differences in the relaxation rate values. Thanks to additional low temperature SQUID and NMR data we show that this plateau occurs concurrently with a freezing transition. Moreover, we revisited the effect of diluting the magnetic lattice for small dilution rates between 1% and 15%. Comparison is made with the well studied kagome bilayer compounds. The ground state of volborthite appears to be far less stable with respect to dilution. (c) 2005 Elsevier B.V. All rights reserved.
