dc.description.abstractThe superconductivity of the Y1-xPrxBa2Cu3O7-[delta] system is quenched as x increases. It has been speculated that praseodymium has a valence of 4+, which results in extra charge in the Cu-O planes, and causes quenching of Tc. To study the electronic state of praseodymium, the valence band resonant photoemission of the Y1-xPrxBa2Cu3O7-[delta] system was measured for x = 0, 0.2, 0.4, 0.6, 0.8 and 1.0. It was found that the praseodymium valence is close to 3+ for all x values and that the extracted Pr 4f spectral weight has a complex line shape. This line shape implies extensive Pr 4f-O 2p/Cu 3d hybridization which probably causes the quenching of Tc by disrupting the electronic or magnetic structure of the x = 0 material, perhaps via Pr-Cu and Pr-O superexchange interactions.en_US
