Zero Field Splitting Parameter of Mn^{2+}-Doped Tl_{2}Cd_{2}(SO_{4})_{3} Single Crystals at Axial Symmetry Site

Abstract

Theoretical study of the crystal field parameters and the zero-field splitting parameter of Mn²⁺-doped langbeinite Tl₂Cd₂(SO₄)₃ single crystals is done using the superposition model and perturbation theory. The zero-field splitting parameter found here matches well with the experimental value. The theoretical study supports the conclusion of experimental study that Mn²⁺ substitutes for Cd²⁺ in Tl₂Cd₂(SO₄)₃ single crystal.
