ac susceptibility and magnetic relaxation of R2PdSi3 (R=Nd, Tb, and Dy) -: art. no. 012413

The results of ac susceptibility and magnetic relaxation measurements on R2PdSi3 (R=Nd, Tb, and Dy), a class of compounds previously shown in the literature to exhibit interesting properties, are reported. The data for the Nd compound show spin-glass-like anomalies at the temperature where long-range ferromagnetic ordering sets in. While we observed two magnetic transitions for Tb and Dy compounds in agreement with the literature, the ones occurring at the lower temperature side is shown to exhibit spin-glass-like anomalies. These results are compared with those reported for other 2:1:3 compounds.
