Recently we have investigated the cubic compound PrRhSn3 using the dc and ac susceptibilities and the heat capacity. We found an evidence for the cluster-glass behavior with a freezing temperature, Tf = 4.3 K. The frequency dependence of Tf is well described by the Vogel-Fulcher law with activation energy Ea = 21.3 K, and within the framework of critical slowing down, we estimated characteristic time constant 2.2 x 10^-10 s and critical exponent 10.86. All these results provide a strong evidence for the formation of a cluster-glass state in PrRhSn3. We believe that the origin of spin-glass behaviour lies in the dynamic fluctuations of the CEF levels as has been proposed for PrAu2Si2. Therefore it would be of interest to confirm the spin-glass behaviour in this compound using muon spin relaxation/rotation technique, which is ideal to probe the spin-glass behaviour.
