We have investigated the electrical resistivity under magnetic fields in the itinerant-electron weak ferromagnet LaFe 4 As 12, in order to clarify the characteristics of spin fluctuations in this material by comparison with the reported typical itinerant-electron ferromagnets. As a common feature to the typical itinerant-electron weak ferromagnets, strong enhancement of negative longitudinal magnetoresistivity was observed near TC, reflecting the suppression of spin fluctuations. As a unique behavior of LaFe 4 As 12, we found a considerable positive component of the magnetoresistivity above TC.
