TL;DR: In this article, a low-energy spin-fluctuation peak position shifts from ($\frac{1}{2}$ to ($ \frac{ 1}{2$\ifmmode\pm\else\textpm\fi{ \ensuremath{\delta}=x$, and the peak momentum width of the spin fluctuations at low energies is small throughout the superconducting concentration region.

TL;DR: In this paper, a spin gap opens up when the n-type cuprate becomes SC, as in the optimally doped p-type La2-xSrxCuO4.

TL;DR: In this paper, high-resolution angle-resolved photoemission spectroscopy of the electron-doped high-temperature superconductor Nd2-xCexCuO4 (x = 0.15, transition temperature Tc = 22 K) has found the quasiparticle signature as well as the anisotropicdx2-y2-like superconducting gap.

TL;DR: In this paper, the effect of heat treatment on the Neel temperature is clearly seen when x exceeds ∼ 0.10 where fractional superconductivity appears by the heat treatment, and it is shown that near the antiferromagnetic-superconducting phase boundary for the heat-treated samples antiferrome magnetism remarkably degrades upon electron-doping.

TL;DR: In this paper, post-growth heat treatments on sizable single crystals of Nd 1.85 Ce 0.15 CuO 4 were performed and two distinct superconducting samples in which T c equals 18 K and 25 K under identical Ce-concentrations.
