| The superposition model is used to investigate the crystal field parameters, Bkq of Cr3+ in lithium potassium sulphate. The zero field splitting parameters D and E are then determined using microscopic spin Hamiltonian theory and compared with the experimental values obtained by electron paramagnetic resonance. Both zero field splitting parameters D and E evaluated theoretically are in good agreement with the experimental values. The results suggest that the Cr3+ ion occupies substitutional K+ site in lithium potassium sulphate. |
