Inhomogeneous reduction-annealing effects on the electron-doped cuprate superconductor Pr1.3-x La0.7CexCuO4 (x=0.08) revealed by microfocused angle-resolved photoemission spectroscopy
The development of the protect-annealing method has extended the superconductivity of the electron-doped cuprate Pr1.3-xLa0.7CexCuO4 (PLCCO) into lower Ce concentrations, while the superconducting volume fraction decreases with underdoping. Employing angle-resolved photoemission spectroscopy with a microfocused beam, we investigated the electronic structure of protect-annealed PLCCO (x=0.08) with
