Abstract
We measured the resistivity of the itinerant ferromagnet as a function of temperature K) and magnetic field kOe) in the vicinity of the ferromagnetic phase transition K). We find that the magnetic resistivity is related to the magnetization M by over a wide range of M. From the analysis of the resistivity data we determine the critical parameters of the phase transition below above Here and are the critical exponents of the spontaneous magnetization and the susceptibility, respectively, and is the amplitude ratio of the susceptibility. Our results are supported by a collapse of the magnetoresistance data on a single curve when an approriate scaling function is used.
