By Roman Boča (auth.), D. M. P. Mingos (eds.)

Using the spin-Hamiltonian formalism the magnetic parameters are brought throughout the parts of the Lambda-tensor related to in basic terms the matrix components of the angular momentum operator. The strength degrees for numerous spins are generated and the modeling of the magnetization, the magnetic susceptibility and the warmth ability is finished. Theoretical formulae useful in appearing the strength point calculations for a multi-term method are ready with assistance from the irreducible tensor operator technique. The objective of the programming lies within the incontrovertible fact that the whole suitable matrix parts (electron repulsion, crystal box, spin-orbit interplay, orbital-Zeeman, and spin-Zeeman operators) are evaluated within the foundation set of free-atom phrases. The modeling of the zero-field splitting is finished at 3 degrees of class. The spin-Hamiltonian formalism deals easy formulae for the magnetic parameters by means of comparing the matrix parts of the angular momentum operator within the foundation set of the crystal-field phrases. The magnetic features for dn complexes are modeled for a variety of the crystal-field strengths.
