Abstract
The results of heat capacity (C), electrical resistivity and Ce LIII-edge measurements on the alloys, Ce2Pd2In, Ce2Rh2In and some of their derivatives, are reported. The temperature dependence of C data of Ce2Pd2In exhibits features attributable to short range magnetic correlations preceding a sharp upturn at 4 K arising from long range magnetic ordering. An increase in Pd/In ratio apparently diminishes the magnetic transition temperature and the features due to spin fluctuation effects. The low temperature values of C/T of Y1.6Ce0.4Pd2In and Lu1.6Ce0.4Pd2In are large, attributable to heavy fermion behavior. In the compound Ce2Rh2In, Ce is found to be strongly mixed valent, with a large spin fluctuation temperature.
