Energy Level Calculation for the Mn 2+ Paramagnetic Impurity Ion in a LiNbO 3 Single Crystal

The ground-state energy levels of the Mn
2+paramagnetic impurity ion which substitutes at Nb
5+ion sites in the ferroelastic LiNbO
3single crystal were calculated when a magnetic field B was applied along the crystallographic principal axes. The Mn
2+ion (effective spin S = 5/2) has six energy levels because of the Zeeman splitting that occurs when the magnetic field is applied. The energy diagrams for the Mn
2+ion calculated when the magnetic field is applied along the crystallographic a- and c-axis are different from each other. The calculated ZFS (zero field splitting) energies of the Mn
2+ion in the LiNbO
3single crystal for the | ± 5/2 > ↔ | ± 3/2 > and the | ± 3/2 > ↔ | ± 1/2 >
transitions are 8.6874 GHz and 4.3629 GHz, respectively.
