Abstract
We report heat-capacity, x-ray, electrical-conductivity, and Seebeck-coefficient measurements in the range K, which indicate that there exist two high-temperature, band-type phases in . The electrical anomaly encountered in this range is considered to be an extrinsic phenomenon, attributed to the coexistence of these phases over a broad temperature range (∼ 300-500 K). The data are inconsistent with any model invoking a metal-insulator transition in this range of temperature.
