We have succeeded in growing single crystals of SmPt2Si2 and have performedelectrical resistivity, magnetization and specific heat measurements. Themagnetic susceptibility shows that SmPt2Si2 is an Ising magnet with thecrystalline-electric-field ground state of Jz=+-3/2. We have found theexistence of two magnetically ordered states, i.e., an antiferromagnetically(AFM) ordered phase (I) setting in at TN=5.1 K and a field-inducedmagnetization plateau phase (II). In the phase I, unlike the usual AFM states,a pronounced Curie-Weiss contribution remains in magnetic susceptibility,indicating the existence of "partially disordered" Sm ions. Largely enhancedSommerfeld-coefficient (350 mJ/K2mol) in the phase I can be attributed toformation of Kondo sublattice with heavy quasiparticles in the partiallydisordered Sm ions. These findings may reflect substantial magneticfrustrations inherent in SmPt2Si2.
