NON-FERMI-LIQUID-LIKE BEHAVIOR IN CE(RU1-XRHX)2SI2 LESS-THAN-OR-EQUAL-TO-X-LESS-THAN-OR-EQUAL-TO-0.5)

We have studied the magnetic properties of the mixed-compound system C e(Ru1-xRhx)(2)Si-2 (0.3 less than or equal to x less than or equal to 0.5) by means of specific heat and magnetization measurements with sin gle-crystalline samples. In the intermediate concentration range, 0.3 less than or equal to x less than or equal to 0.5, we observed non-Fer mi-liquid-like behavior in the temperature dependence of the magnetic specific heat. We compare the temperature dependence of the susceptibi lities with the results of the calculation by the crystalline electric field model. Below about 100 K the susceptibilities deviate downward from the calculation; this means that the Kondo effect exists in the i ntermediate concentration range. (C) 1998 Elsevier Science B.V.
