Interpretation of Inelastic Neutron Scattering Data Using the Phase Diagram of Hole-Doped Cuprates
نویسنده
چکیده
Inelastic Neutron Scattering (INS) data in La2-xSrxCuO4 (LSCO), YBa2Cu3O6+x (YBCO) and Bi2Sr2CaCu2O8+x (Bi2212) are discussed. In the literature, the INS spectra remain far from being comprehensively understood. We show that local (Q-integrated) susceptibility data and the energy dependence of the spin susceptibility at antiferromagnetic vector, QAF = (π,π), can be interpreted by using the phase diagram for hole-doped cuprates. We analyze also the origin of the resonant peak which relates to the order parameter for long-range phase coherence in hole-doped cuprates. Thus, we present an interpretation of neutron data in LSCO, YBCO and Bi2212 published so far. PACS: 74.25.Dw, 74.25.Ha, 74.72-h

The Magnetic Origin of the Coherent Order Parameter in Hole- Doped Cuprates
The phase diagram for hole-doped cuprates is discussed. By examining some recent inelastic neutron scattering data obtained on hole-doped cuprates we conclude that the coherent gap in hole-doped cuprates has most likely the magnetic origin and scales with Tc, on average, as 2∆c/kBTc = 5.4.

Extending our previous studies we present results for the doping, momentum, frequency, and temperature dependence of the kinklike change of the quasiparticle velocity resulting from the coupling to spin fluctuations. In the nodal direction a kink is found in both the normal and superconducting state while in the antinodal direction a kink occurs only below Tc due to the opening of the supercond...

Neutron scattering is proved to be a vital probe in unveiling the magnetic properties of high temperature superconductors (HTSC). Detailed information about the energy and momentum dependence of the magnetic dynamics of HTSC have been obtained directly by this technique. Over the past decade by improving the crystal growth methods, large and high quality single crystals of HTSC, which are ess...
