Abstract: | The spin-Hamiltonian zero-field splitting parameter b(2)(0) is measured as a function of temperature in Mn2+ doped Cs2NaLaCl6 single crystals (elpasolite type). The experiments showed that the Mn2+ ion occupies two different tetragonal symmetry sites in the cubic crystalline lattice of Cs2NaLaCl6. Both sites possess principal Zaxes 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. (C) 1997 Elsevier Science Ltd. |
