Perturbative Method

A two-level crystal field model in the presence of the phonon field is considered. Spins are arranged on a lattice and weakly coupled to the lattice oscillations of small amplitudes. The anticommutator Green function perturbative method up to the second order in the coupling constant is applied to find thermodynamical quantities. The magnetic spectral function, describing the crystal field excitations, influences these quantities. The effect is studied numerically and illustrated in figures. In particular, the influence of the coupling on the Schottky specific heat is shown.

Abstract The paramagnetic susceptibility behaviour as well as the Mössbauer quadrupole splitting are calculated for high-spin d6 systems with a tetragonal or an orthorhombic point-symmetry. The calculations include a simultaneous perturbation of the 5D multiplet by spin-orbit interaction and static octahedral-tetragonal and orthorhombic fields. The lattice contribution to the electric-field gradient is calculated on the basis of a crystal-field model that directly relates crystal-field energy parameters to the lattice contribution. It appears that, espacially for compounds with large Ds values, the lattice contribution to the quadrupole splitting cannot be ignored.
