Abstract
The spin-Hamiltonian zero-field splitting parameter b 2 0 is measured as a function of temperature in Mn 2+ doped Cs 2NaLaCl 6 single crystals (elpasolite type). The experiments showed that the Mn 2+ ion occupies two different tetragonal symmetry sites in the cubic crystalline lattice of Cs 2NaLaCl 6. Both sites possess principal Z-axes along 〈100〉 crystallographic directions. Electron spin resonance measurements were made at X-band frequencies (9.2 GHz) in the temperature range from 12.8 to 300 K. The present results are taken into account in order to establish a possible relation between the spin-Hamiltonian parameter b 2 0 and the temperature. A tentative determination of the Debye temperature is derived from the experimental data.
