Abstract

Dynamical spin fluctuations in SrCr8−xGa4+xO19 a frustrated spin system on a kagomé lattice, is examined by the longitudinal field muon spin relaxation technique. This system shows a spin-glass (SG)-like cusp in the susceptibility atTg=3.5(2) K. The slowing down of Cr spin fluctuations is found to occur over a very wide temperature rangeTg<T<30Tg. AsT/Tg → 0 these fluctuations remain without static polarization (order parameter). Such strong fluctuations belowTg have not been observed before in a conventional SG system.
