TL;DR: Inelastic neutron scattering experiments have been carried out on YBa2Cu3O6+x single crystals in order to perform a systematic investigation of the spin dynamics in the various typical regimes as discussed by the authors.

TL;DR: The spontaneous onset of a one-dimensional, incommensurate modulation of the spin system in the high-transition-temperature superconductor YBa2Cu3O6 suggests that soft spin fluctuations are a microscopic route toward electronic liquid crystals and that nematic order can coexist with high-tem temperature superconductivity in underdoped cuprates.

TL;DR: In this article, a neutron scattering study reveals that the magnetic fluctuations in an iron arsenide superconductor behave according to the conventional theories of metals, unlike the cuprate superconductors, and the magnetic spin-excitation energies are sufficient to mediate the Cooper pairs that form the superconducting state.

TL;DR: In this paper, inelastic neutron scattering measurements of a different copper oxide system (Bi2Sr2CaCu2O8+δ) were performed, in which they observed a magnetic resonance peak in the superconducting state.

TL;DR: The results support recent theoretical proposals that both nematicity and superconductivity are driven by spin fluctuations.
