From 20 to 300K, the temperature dependence of the resistance is well described by a law of the form a+bT 4/3 , theoretically predicted to occur in the presence of ferromagnetic fluctuations. In addition, this prediction is reinforced by the analysis of the transverse and the longitudinal low T magnetoresistance. Interestingly, the presence of a weak disorder causing low T electronic localization allows us to evidence very short diffusion lengths, as observed in other systems with ferromagnetic fluctuations. %G English %2 https://universite-paris-saclay.hal.science/hal-04066452/document %2 https://universite-paris-saclay.hal.science/hal-04066452/file/Paper_VOD_ARXIV_CD.pdf %L hal-04066452 %U https://universite-paris-saclay.hal.science/hal-04066452 %~ CNRS %~ UNIV-PARIS-SACLAY %~ UNIVERSITE-PARIS-SACLAY %~ GS-CHIMIE %~ GS-PHYSIQUE %~ GS-LIFE-SCIENCES-HEALTH %~ LPSO
