2-D and Mott Transition Studies on Metal (M) Doped PrBa2Cu3O7

We doped PrBa2Cu3O7 (PBCO) using various metals (M) to obtain PrBa2[Cu(1−x)M x ]O7 (PBCMO) ceramic samples and epitaxial thin films. As suggested in the above chemical composition, these samples were made by replacing some of the Cu ions in PBCO with its metallic neighbors (M) such as Al, Co, Fe, Ga, Ni, and Zn at four different doping concentrations (x)—0.05, 0.10, 0.15, and 0.20. The epitaxial films were made by performing laser ablation on a ceramic disk target. We also present the results of our transport and Raman studies on the aforementioned PBCMO samples.
