TL;DR: Be measuring the degree of linear polarization, the orbital and spin contributions to the x-ray magnetic scattering in holmium are identified and a fiftyfold resonant enhancement of the magnetic signal, and resonant integer harmonics are observed.

TL;DR: Inelastic neutron scattering experiments have been carried out on YBa2Cu3O6+x single crystals to investigate the spin dynamics in the pure AF-state (x = 0.15, TN = 410 K), in the doped AF state (x= 0.37, Tc = 180 K), and in the metallic weakly doped superconducting state (tc = 37 K; x =0.51, tc = 47 K).

TL;DR: In this article, inelastic neutron scattering experiments performed on single crystals of the heavy fermion compounds CeRu2Si2 and CeCu6 were performed on both compounds.

TL;DR: In this paper, the authors provided an approximate value for the energy gap: EG≂0.4/k ≈−50 K, where J is the intrachain exchange interaction, which is consistent with the Haldane conjecture.

TL;DR: In this article, the unusual properties of CeSb are reviewed and new results presented, in particular the magnetic phase diagram has been investigated under high magnetic fields where a new phase FP′ (+++0) has been discovered and under high pressure which increases strongly TN (TN = 30.5 K at P = 21 kbar), changes the ordering to type I and suppresses the non-magnetic planes.
