The Neel temperature of heavy fermion material CeIn3 is at 10 K. La doping to Ce site of CeIn3 introduces increase of distance between Ce ions and reduction of number of 4f electron. It is implied the reduction of 4f electron number with La doping weakens inter site magnetic interaction. An x-T phase diagram was drawn with Neel temperatures estimated from both electrical resistivity and magnetic susceptibility measurements. (c) 2006 Elsevier B.V. All rights reserved.
