Abstract

This chapter provides a detailed account of the key assumptions underlying the superposition model as well as the systematic derivation of its relevant formulas for the d-shell electronic configurations. Besides, examples and remarks are given for the specific applications of the superposition model to deal with local distortion or lattice relaxation, spin-Hamiltonian parameters, and orbit-lattice interaction when transition metal ions are doped in various crystal hosts.
