Abstract

This paper examines X-ray diffraction, DC electrical resistivity, DC and AC magnetic susceptibilities, specific heat and the Ce L III-edge X-ray absorption spectrum of the cerium-based ternary compound, CePdSi 2. Electrical resistivity, ρ( T), indicates the presence of Kondo and crystal-field effects. The results of magnetic susceptibility measurements for CePdSi 2 exhibit antiferromagnetism at 2.7 and 6.8 K. The specific heat measurement also shows these two corresponding peaks in C( T). Besides, we found spin-glass behaviors in the magnetic susceptibility measurements. The time dependence of magnetization observed and magnetic entropy calculations also agree with the presence of spin-glass phase.
