Journal ArticleDOI
Depression of superconductivity, heavy fermion behavior and valence fluctuations in Y1−xPrxBa2Cu3O7
Chan-Soo Jee,Abebe Kebede,D. Nichols,J. E. Crow,T. Mihalisin,G.H. Myer,I. Perez,R. E. Salomon,Pedro Schlottmann +8 more
TL;DR: The specific heat, magnetization, susceptibility and electrical resistivity of Y1-xPrxBa2Cu3O7 are presented in this paper, where the authors show that Pr depresses Tc and causes a transition from metallic to semiconducting behavior at x ∼ 0.6.
Journal ArticleDOI
d-Hole localization and the suppression of superconductivity in YBa2(Cu1-xZnx)3O7−y
Chan Soo Jee,D. Nichols,Abebe Kebede,S. Rahman,J.E. Crow,A.M.Ponte Goncalves,T. Mihalisin,G.H. Myer,I. Perez,R. E. Salomon,Pedro Schlottmann,S. H. Bloom,M. V. Kuric,Y. S. Yao,Robert P. Guertin +14 more
TL;DR: In this article, the substitution of Zn for Cu in YBa2Cu3O7−ycffff withy∼0.16 for both the superconducting and nonsuperconducting samples was shown to cause a rapid and nearly linear depression of the transition temperature.
Journal ArticleDOI
Magnetic and thermodynamic properties of nonsuperconducting (Y,Pr)Ba2Cu3O6
Abebe Kebede,J. P. Rodriquez,I. Perez,T. Mihalisin,G.H. Myer,J. E. Crow,P. P. Wise,Pedro Schlottmann +7 more
TL;DR: In this article, the concentration and temperature dependence of the specific heat C(T) and the magnetic susceptibility have been measured on the tetragonal, nonsuperconducting phase of Y1−xPrxBa2Cu3O6.
Journal ArticleDOI
Preparation of YBa 2 Cu 3 O 7− x using barium hydroxide flux
TL;DR: In this article, high quality bulk YBa 2 Cu 3 O 7−x was synthesized by fusing stoichiometric amounts of yttrium and copper nitrates and barium hydroxide in air, using an ordinary Bunsen burner.
Journal ArticleDOI
(Y,Pr)Ba2Cu3O7: Evidence for AG pair breaking in a high Tc superconductor
Abebe Kebede,Abebe Kebede,Chan-Soo Jee,Chan-Soo Jee,D. Nichols,D. Nichols,M.V. Kuric,M.V. Kuric,J.E. Crow,J.E. Crow,R.P. Guertin,R.P. Guertin,T. Mihalisin,T. Mihalisin,G.H. Myer,G.H. Myer,I. Perez,I. Perez,R. E. Salomon,R. E. Salomon,Pedro Schlottmann,Pedro Schlottmann +21 more
TL;DR: In this paper, the superconducting transition temperature for rare earth substituted YBa 2 Cu 3 O 7 compounds is depressed with increasing x, following closely the dependence predicted by Abrikosov-Gor'kov's pair breaking theory.
