Spin Response

Within the kinetic energy driven superconducting mechanism, the dynamical spin response of the bilayer cuprate superconductors is studied. It is shown that there are two nondegenerate magnetic modes with odd and even symmetries, respectively, due to the bilayer interaction in the bilayer cuprate superconductors. Although the magnetic scattering in both odd and even symmetries shows an hour-glass-shaped dispersion, the commensurate magnetic resonance energy in the odd symmetry has a domelike shape of the doping dependence, while the commensurate magnetic resonance energy in the even symmetry decreases with increasing doping.

Gap Parameter

Within the kinetic energy driven superconducting mechanism, we have studied the temperature dependence of commensurate magnetic resonance in cuprate superconductors. It is shown that the commensurate magnetic resonance peak at the antiferromagnetic wave vector point persists in the superconducting state until the temperature rises to the superconducting transition temperature $T_{\rm c}$. The intensity of the resonance peak decreases with increasing temperature which is just like the temperature dependence of the superconducting gap parameter. Our results are in qualitative agreement with the inelastic neutron scattering experimental data and reflect that the commensurate magnetic resonance is closely related to the creation of the charge carrier pairs and thus the superconducting mechanism of cuprate superconductors.
