Abstract
Magnetic-susceptibility and electrical-resistivity measurements on CePdSb and GdPdSb have been carried out in the temperature range of 4.2300 K. The measurements reveal that CePdSb orders ferromagnetically with an ordering temperature (TM) of 17 K while GdPdSb orders antiferromagnetically with a Néel temperature (TN) of 15.5 K. In the paramagnetic state, the susceptibility of CePdSb follows Curie-Weiss behavior between 50 and 300 K but deviates from it below 50 K. Its saturation magnetic moment per formula unit at 4.2 K is 1.2B, which is reduced from the free-ion value of 2.14B for the Ce3+ ion. The resistivity of CePdSb shows a broad maximum at about 150 K and a ln(T) behavior at high temperatures, indicating the combined influence of crystalline electric fields and Kondo effect on the 4f moments. Thus CePdSb appears to be a Kondo-lattice system with ferromagnetic ordering of the cerium moments.
