Modeling of Cr^{3+}-Doped Cs_{2}CdCl_{4} Single Crystal

Abstract

Crystal field parameters of the Cr³⁺-doped Cs₂CdCl₄ single crystal are determined by the superposition model. The zero-field splitting parameter D is then evaluated employing microscopic spin Hamiltonian theory. The theoretical zero-field splitting parameter for Cr³⁺ in Cs₂CdCl₄ single crystal at the axial symmetry site is in good agreement with the experimental value. The local distortion is considered to find the crystal field parameters.
