Aluminum Incorporation in Cuprate Perovskites
Published online by Cambridge University Press: 28 February 2011
Abstract
Aluminum incorporation in cuprate perovskite single crystals has been studied by single crystal x-ray diffraction. We find that Al substitutes for copper in the Cu-O chains only. Superconducting transition temperatures, Tc, determined by dc diamagnetic susceptibility measurements, change only slightly, to «80K for ×=0.l, then drop sharply with higher aluminum concentrations.
