The samples have very narrow rocking curves and excellent in plane registry with the substrate. A strong correlation between the peak resistance temperature and the polaronic hopping energy is seen which is not simply linear. The low temperature resistivity is seen to be fit better by a model of single magnon scattering, and a near linear correlation between the resistivity due to magnon scattering and static impurities is observed.12 pages, 7 figuresStrongly Correlated ElectronsMaterials Sciencetext
