Superconductivity and thermal fluctuation of Y<inf>1-x</inf> M<inf>x</inf>: 123 systems with (M = Pr,Ca) & (0.00 < x < 0.50): Comparative study
2021, Physica B: Condensed MatterCitation Excerpt :The altering of superconductivity by Pr in Y1-x Prx:123 systems has mostly been attributed to the possible different valence states of Pr such as Pr+3, Pr+4 and Pr3+/4+ [28–32]. But there are also some other reasons regardless of the valence state, such as copper pair breaking results from Pr magnetic moment and strong hybridization between (Pr-4f) and (O–2P) conduction band electrons, which may lead to localization of hole carriers and also offers a possibility for altering superconductivity in Y1-x Prx:123 [33–35]. Moreover, an increase in the formation of oxygen vacancies in the Cu–O2 planes has been recorded in the Y1-x Prx:123 systems [36,37].
