The Spin Excitation Spectrum in Superconducting
P. Bourges, Y. Sidis, H. F. Fong +4
A comprehensive inelastic neutron scattering study of magnetic excitations in the near-optimally doped high-temperature superconductor is presented. T…
Quantum Impurities and the Neutron Resonance Peak in : Ni versus Zn
Y. Sidis, P. Bourges, H. F. Fong +9
The influence of magnetic (S=1) and nonmagnetic (S=0) impurities on the spin dynamics of an optimally doped high temperature superconductor is compared in two samples with almost i…
Spin Susceptibility in Underdoped
H. F. Fong, P. Bourges, Y. Sidis +6
We report a comprehensive polarized and unpolarized neutron scattering study of the evolution of the dynamical spin susceptibility with temperature and doping in three underdoped s…
Spin dynamics in high- superconductors
Ph. Bourges, Y. Sidis, H. F. Fong +6
Key features of antiferromagnetic dynamical correlations in high- superconductors cuprates are discussed. In underdoped regime, the sharp resonance peak, occuring exclusively…
Neutron Scattering from Magnetic Excitations in Bi_2 Sr_2 Ca_2 O_8+delta
H. F. Fong, P. Bourges, Y. Sidis +5
Many physical properties of the copper oxide high temperature superconductors appear to defy the conventional (one-electron) theory of metals, and the development of new theories i…
Effect of Nonmagnetic Impurities on the Magnetic Resonance Peak in YBa2Cu3O7
H. F. Fong, P. Bourges, Y. Sidis +6
The magnetic excitation spectrum of a YBa_2 Cu_3 O_7 crystal containing 0.5% of nonmagnetic (Zn) impurities has been determined by inelastic neutron scattering. Whereas in the pure…
