Eremin MV, Effects of exchange-covalent bonds on the orbital moment of paramagnetic centers with unfilled 3d-shells//MAGNETIC RESONANCE IN SOLIDS. - 2024. - Vol.26, Is.1. - Art. �24101.

Annotation

An effective operator of the interaction of the orbital moment of d-electrons with the magnetic field is derived by combining the method of secondary quantization with the technique of irreducible tensor operators. It is found that in addition to renormalization of the matrix elements of the total orbital momentum L there are new terms in the Hamiltonian of the interaction with the magnetic field. The effects are numerically calculated by the example of the ground term of Fe2+ ions in Fe2Mo2O8. Additional magnetic dipole transitions with ΔM = ?3 and ΔM = ?2 are allowed when the magnetic field is directed along the c-axis of the crystal and in the perpendicular orientation, respectively.
