The recent discovery of a new heavy-fermions (HF) family, CeMIn5 (M=Ir, Rh, Co), raises once again the long-lasting question about the relation between magnetic and superconducting (SC) interactions. CeCoIn5 has Tc=2.3 K and is believed to reside close to a quantum critical point (QCP). Although no long-range magnetic order is present, short-range AF spin fluctuations are observed. In order to understand the interplay between superconductivity and spin fluctuations in CeCoIn5 we have performed c-axis magnetotransport measurements between 40 mK and 300 K and in the fields up to 9 T, applied along c-axis.
