| Abstract: | Dynamic susceptibility measurements on HoRh1.2Sn3.9 have been performed in the vicinity of its magnetic transition at TM = 1.7 K. χ'(T) exhibits a cusp-like peak, which is substantially depressed when an external field of a few mT is applied. Below TM a strong frequency dependence of the susceptibility is found. The results are very similar to those of classical spin glass behaviour for HoRh1.2Sn3.9. Results on other phase II ternary stannides as, e.g., the reentrant magnetic superconductor ErRh1.1Sn3.6 may be interpreted likewise. |
