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.
Journal ArticleDOI
Magnetic, transport, and optical properties of monolayer copper oxides
TL;DR: In this paper, the authors review the results of a wide variety of experiments on materials such as weakly coupled antiferromagnetic insulators with very large Heisenberg exchange energies, which become high-temperature superconductors when charge carriers are added to the layers.
Journal ArticleDOI
Two-dimensional antiferromagnetic quantum spin-fluid state in La2CuO

TL;DR: Elastic, quasielastic, and inelastic neutron scattering measurements in La 2 CuO 4 reveal novel two-dimensional antiferromagnetic behavior that is relevant to the high-temperature superconductivity in this class of materials.
Journal ArticleDOI
Magnetic phase diagram and magnetic pairing in doped La2CuO
TL;DR: The temperature-concentration phase diagram of doped La/sub 2/CuO/sub 4/.
Journal ArticleDOI
Magnetic excitations in pure, lightly doped, and weakly metallic La2CuO4.
