Abstract

The new ternary intermetallic compound Tb₂PtSi₃ crystallizing in the ordered hexagonal structure has been studied by means of susceptibility, magnetization, magnetic relaxation, specific heat and electrical resistivity measurements. The results reveal that Tb₂PtSi ₃ orders ferromag- netically below T_c=22 K and undergoes an additional magnetic phase transition near T₁=10 K. The distribution of two kinds of Tb atoms at crystallographically non-equivalent positions seems to be responsible for the complex magnetic structure. Below T_c, clearly irreversible magnetism and the phenomenon of long time magnetic relaxation are observed in this system and discussed in terms of domain-wall pinning effects.
