Energy Level Diagram, Wavefunctions, and Probabilities of Optical Transitions in KCuF_(3)

摘要

Using modern concepts of the crystal field in ion-covalent compounds, we calculate the energy level diagram, wavefunctions, and probabilities of optical transitions in the orbital ordering phase of KCuF_(3). On this basis, we discuss the possible mechanisms by which an optical absorption sideband structure forms, accompanied by the creation of magnons.
