Abstract
We have examined the magnetic properties of the frustrated kagome latt ice spin systems KFe3(OH)(6)(SO4)(2) (Fe-jarosite) and KCr3(OH)(6)(SO4 )(2) (Cr-jarosite) using the mu SR technique. In Fe-jarosite, a clear muon precession signal in zero field was found below 55 K, correspondi ng to the long-range order of Fe moments. In Cr-jarosite spin fluctuat ions persist without clear signature of spin freezing even at T = 25 m K, far below T-g similar to 2 K where the history dependence in the ma gnetic susceptibility appears.
