Abstract

We derive an anisotropy energy VA, a spin-atomic vibration interaction VSA, and a spin-flip Hamiltonian VSF of a single atomic spin system, "Fe2+ (3d6) in a crystal field of tetragonal symmetry". The perturbation theory is here applied to the system with the spin-orbit interaction and the kinetic and potential energies, in which difference of vibration displacement between a nucleus and electrons is taken into account. We first find conditions to enhance a coefficient |D
