Superconductivity at 9–15 K was recently discovered in Nd0.8Sr0.2NiO2 films. Since the Ni1+ ionic state in NdNiO2 may have the same 3d9 outer-shell electronic orbital as in cuprate superconductors, it is interesting to know whether superconductivity has a similar mechanism in these two systems. Here we synthesize bulk samples of Nd1−xSrxNiO2 (x = 0, 0.2, 0.4) with inhomogeneous Sr distribution and Ni deficiency. Resistivity measurements show insulating behavior without the presence of… Expand

Scale-free structural organization of oxygen interstitials in La2CuO4+y
TLDR
It is reported that the ordering of oxygen interstitials in the La2O2+y spacer layers of La2CuO4+y high-Tc superconductors is characterized by a fractal distribution up to a maximum limiting size of 400 μm, and intriguingly, these fractal distributions of dopants seem to enhance superconductivity at high temperature.

TLDR
This work applies synchrotron hard X-ray nanoimaging and small-angle scattering to reveal a novel micron-scaled ribbon phase in optimally doped Bi2Sr2CaCu2O8+δ, which indicates that the optimal TC is affected not only by an optimal morphology of the ribbon phase, but also an optimal distribution of oxygen vacancies.
