Competition between magnetic ordering and random spin freezing in Dy$$_2$$PtS$$_3$$

We report the results for ac and dc susceptibility, magnetization, magnetic relaxation, specific heat and electrical resistivity measurements on a well annealed ternary intermetallic compound Dy$$_2$$PtSi$$_3$$. An unusual magnetic phase transition with an apparent ferromagnetic nature was observed at $$T_{rm C}$$ = 5.6 K. The classification of Dy$$_2$$PtSi$$_3$$ as a large magnetic cluster (extended short-range ferromagnetic ordered) system with competition between magnetic ordering and random spin freezing seems appropriate.
