- W2000285426 abstract "This study explores issues connected with the complex structural and electronic behavior of partly substituted YBa2(Cu1−x−zFexZnz)3Oy when given special redox sequencing over varying times. For z=0 and x=0.03 conventional oxygenating slow cooling preparations (OP) yield tetragonal materials with Tc-mid=59K. Getter annealing procedures using Gd to control the extent of reduction to y=6.1 at 1000K for 4 days followed by reoxidation at 700K for 1 hour yield orthorhombic materials with Tc-mid=68K and improved superconducting volume fractions. The results are in line with expectations for the presence of ordered atomic size Fe clusters with these reducing preparations (RP). This redox sequence also reduces the paramagnetic Curie temperature from Θp=−35K to Θp=−51K for z=0, hinting at higher cluster Neel temperatures. When the getter annealed specimen is air annealed for prolonged times (50h) at 673K, a broader Tc transition develops and a slight decrease in the orthorhombic splitting is observed. This demonstrates that small rearrangements from properties of RP to OP are possible even at these low temperatures. Codoping to x=0.03, z=0.01 results in drastic reductions to Tc-mid=31K for OP, beyond the one expected from individual contributions, while structural parameters do not change noticeably. This synergistic effect is also reflected in Θp and may have to do with a large proportion of Fe occupying the Cu(2) site. Results are discussed within models of inhomogeneous M distributions and oxygen chain order." @default.
