Doping evolution of the magnetic excitations in the monolayer CuO.

In this paper, we study theoretically the doping evolution behaviors of the magnetic excitations (MEs) in the monolayer CuOgrown on BiSrCaCuOsubstrate. For the undoped system, the MEs exhibit the low energy commensurate behavior around (,). They turn to be incommensurate when the system is slightly hole-doped.
