摘要

X-ray absorption near edge structure (XANES), resistivity, and thermoelectric power have been measured on Pr_1-xCa_xBa₂Cu₃O₇. These data reveal an intriguing electronic structure in Pr-doped cuprates. The absorption peak in XANES associated with the Fehrenbacher-Rice (FR) band has been identified. The Ca-doped holes in Pr_1-xCa_xBa₂Cu₃O₇ go to both the Zhang-Rice (ZR) and FR bands. Comparative studies on the related samples suggest that the FR band is partially filled and highly localized. Implications of these results on other recent experiments, such as the observation of superconductivity in PrBa₂Cu₃O₇ single crystals, are discussed.
