摘要
SrRuO3 is an itinerant ferromagnet with T-c similar to 160 K and a 'bad metal' in the limit of k(F)l = O(1). While the magnetic properties of SrRuO3 in the paramagnetic phase, near the ferromagnetic phase transition and at low temperatures are normal and consistent with its being a strong itinerant ferromagnet, the transport properties (resistivity and magnetoresistance) sharply deviate from that of good metallic ferromagnets. We conjecture that the distinct transport behaviour of SrRuO3 is related to its being a 'bad metal' in the k(F)l = O(1) limit, and discuss the possible relevance of our results to the unusual transport properties of other 'bad metals' such as high-temperature superconductors.
