We want to discuss about the growth of CeIn3 nanowires and its characterization using the metallic flux nanonucleation method recently developed by the GPOMS and LMBT groups at IFGW-UNICAMP [1-2]. With this technique, we will study the properties of the CeIn3, a heavy fermion antiferromagnet compound with TN = 10K, as a function of the nanowires diameter ranging from 15 to 200 nm [3-4]. In this talk, we will introduce measurements of microscopy, magnetic susceptibility and EDS, with the intent of explore how the RRKY interactions, CEF and Kondo effects present in CeIn3 evolve as a function of dimensionality [5].[1] Pirota, K.
