Single crystals of the new compound CeCu0.18Al0.24Si1.58 have been grown byhigh-temperature solution growth method using a eutectic Al-Si mixture as flux.This compound is derived from the binary CeSi2 (tetragonal ThSi2-type, Pearsonsymbol tI12, space group I41/amd) obtained by partial substitution of Si by Cuand Al atoms but showing full occupation of the Si crystal site (8e). WhileCeSi2 is a well-known valence-fluctuating paramagnetic compound, theCeCu0.18Al0.24Si1.58 phase orders ferromagnetically at TC = 9.3 K. At lowtemperatures the easy-axis of magnetization is along the a-axis, whichre-orients itself along the c-axis above 30 K. The presence of hysteresis inthe magnetization curve, negative temperature coefficient of resistivity athigh temperatures, reduced jump in the heat capacity and a relatively lowerentropy released up to the ordering temperature, and enhanced Sommerfeldcoefficient (~100 mJ/mol K2) show that CeCu0.18Al0.24Si1.58 is a Kondo latticeferromagnetic, moderate heavy fermion compound. Analysis of the hightemperature heat capacity data in the paramagnetic region lets us infer thatthe crystal electric field split doublet levels are located at 178 and 357 K,respectively, and Kondo temperature (8.4 K) is of the order of TC inCeCu0.18Al0.24Si1.58.
