Abstract
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 Dy2PtSi3. An unusual magnetic phase transition with an apparent ferromagnetic nature was observed at T C = 5.6 K. At temperatures below T C , however, Dy2PtSi3 showed a metastable magnetic behavior characteristic of a typical cluster glass. The classification of Dy2PtSi3 as a large magnetic cluster (extended short-range ferromagnetic ordered) system with competition between magnetic ordering and random spin freezing seems appropriate.Keywords
