摘要：

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