Transport and magnetic properties in the ternary intermetallic compound CePdSi2

This paper examines X-ray diffraction, DC electrical resistivity, DC and AC magnetic susceptibilities, specific heat and the Ce L-III-edge X-ray absor ption spectrum of the cerium-based ternary compound, CePdSi2. Electrical re sistivity, p(T), indicates the presence of Kondo and crystal-field effects. The results of magnetic susceptibility measurements for CePdSi2 exhibit an tiferromagnetism 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 behavi ors in the magnetic susceptibility measurements. The time dependence of mag netization observed and magnetic entropy calculations also agree with the p resence of spinglass phase. (C) 2001 Elsevier Science B.V. All rights reser ved.
