Structure of neutral acceptors in insulating La2CuO4
Gogolin A. O. , Ioselevich A. S.
The energy-level diagram for a hole in La2Cu04, which is bound to an acceptor which replaces La or Cu, is calculated. The hole is described by the Emery model and the impurity level is assumed to be a deep level. The vibronic effects have been studied. The conditions for the formation of the dipole and magnetic frustrating moments of the impurity state due to the Jahn-Teller distortions have been determined.
