Atomic-scale identification of novel planar defect phases in heteroepitaxial YBaCuO thin films
Nicolas Gauquelin, Hao Zhang, Guozhen Zhu +2
We have discovered two novel types of planar defects that appear in heteroepitaxial YBaCuO (YBCO123) thin films, grown by pulsed-laser deposition (PLD) either with…
Synthesis of high-oxidation Y-Ba-Cu-O phases in superoxygenated thin films
H. Zhang, N. Gauquelin, C. McMahon +3
It is known that solid-state reaction in high-pressure oxygen can stabilize high-oxidation phases of Y-Ba-Cu-O superconductors in powder form. We extend this superoxygenation conce…
Attenuation of superconductivity in manganite/cuprate heterostructures by epitaxially-induced CuO intergrowths
H. Zhang, N. Gauquelin, G. A. Botton +1
We examine the effect of CuO intergrowths on the superconductivity in epitaxial La_{2/3}Ca_{1/3}MnO_3/YBa_2Cu_3O_{7-δ} (LCMO/YBCO) thin-film heterostructures. Scanning transmission…
Scanning tunneling spectroscopy study of c-axis proximity effect in epitaxial bilayer manganite/cuprate thin films
I. Fridman, L. Gunawan, G. A. Botton +1
Recent experimental studies have indicated novel superconducting proximity effects in thin-film heterostructures comprising ferromagnetic manganites and superconducting cuprates. T…
