Abstract
is an itinerant ferromagnet with . While the magnetization shows critical behavior that is well fit with universal critical exponents, the temperature derivative of the resistivity shows an unusually strong divergence as with critical exponents higher than 0.9 and very weak divergence as . At low temperatures, the resistivity rapidly increases with temperature, and an unusual correlation with magnetization is found. We argue that the two phenomena stem from the fact that is an inherently bad metal.
