Discovery of Orbital Ordering in Bi2Sr2CaCu2O8+x

Kavli Affiliate: J. C. Seamus Davis | First 5 Authors: Shuqiu Wang, Niall Kennedy, Kazuhiro Fujita, Shin-ichi Uchida, Hiroshi Eisaki | Summary: The primordial ingredient of cuprate superconductivity is the CuO2 unit cell. Here, theoretical attention usually concentrates on the intra-atom Coulombic interactions dominating the 3d9 and 3d10 configurations of each copper ion. However, if […]

Limits to the strain engineering of layered square-planar nickelate thin films

Kavli Affiliate: Lena F. Kourkoutis | First 5 Authors: Dan Ferenc Segedin, Berit H. Goodge, Grace A. Pan, Qi Song, Harrison LaBollita | Summary: The layered square-planar nickelates, Nd$_{n+1}$Ni$_{n}$O$_{2n+2}$, are an appealing system to tune the electronic properties of square-planar nickelates via dimensionality; indeed, superconductivity was recently observed in Nd$_{6}$Ni$_{5}$O$_{12}$ thin films. Here, we investigate […]
