Doping and energy evolution of spin dynamics in the electron-doped cuprate superconductor Pr${}_{0.88}$LaCe${}_{0.12}$CuO${}_{4-\delta }$

Abstract

The doping and energy evolution of the magnetic excitations of the electron-doped cuprate superconductor Pr${}_{0.88}$LaCe${}_{0.12}$CuO${}_{4-\delta }$ in the superconducting state is studied based on the kinetic energy driven superconducting mechanism. It is shown that there is a broad commensurate scattering peak at low energy, then the resonance energy is located among this low energy commensurate scattering range. This low energy commensurate scattering disperses outward into a continuous ring-like incommensurate scattering at high energy. The theory also predicts a dome shaped doping dependent resonance energy.
