Description
Summary:碩士 === 國立中正大學 === 物理所 === 93 === We present the results of lattice parameters at room temperature﹐the static magnetic susceptibility and the magnetic resistivity between 1.8 and 300 K﹐and the low-temperature specific-heat measurements for the series Ce(Pt1-XPdX)Ga﹐﹙x= 0.0,0.2,0.5,0.8 and 1.0﹚﹐Two maxima in the temperature dependence of the magnetic resistive curve for each sample are observed 100 K﹐and another at around 4 K﹐which due to an interplay between crystal-field effect and the Kondo effect﹐As determined from the peak values of the temperature dependence of specific heat data C(T)﹐all samples exhibit antiferromagnetic ordering from 1.3 K for CePdGa to 3.4 K for CePtGa﹒The large reduction of entropy for each sample below TN is associated with Kondo effect﹒
