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…
Nematicity in stripe ordered cuprates probed via resonant x-ray scattering
A. J. Achkar, M. Zwiebler, Christopher McMahon +12
In underdoped cuprate superconductors, a rich competition occurs between superconductivity and charge density wave (CDW) order. Whether rotational symmetry breaking (nematicity) oc…
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…
Resonant X-Ray Scattering Measurements of a Spatial Modulation of the Cu 3d and O 2p Energies in Stripe-Ordered Cuprate Superconductors
A. J. Achkar, F. He, R. Sutarto +4
A prevailing description of the stripe phase in underdoped cuprate superconductors is that the charge carriers (holes) phase segregate on a microscopic scale into hole rich and hol…
