CRYSTAL LATTICE DYNAMIC EFFECTS FOR SASD TYPE CRYSTALS DOPED WITH Cr3+ AS DETECTED BY EPR FOR T > Tc

The effect of lattice vibration on the value of the Dzz parameter for SASD type crystals doped with Cr3' is discussed. It is shown that even for the temperatures much higher than Tc, the inclusion of short and long range correlations taking place for two inequivalent active groups SO,(1)(Se04(1...

Zusammenfassung:The effect of lattice vibration on the value of the Dzz parameter for SASD type crystals doped with Cr3' is discussed. It is shown that even for the temperatures much higher than Tc, the inclusion of short and long range correlations taking place for two inequivalent active groups SO,(1)(Se04(1)) and SO,(11)(Se04(11)) modify temperature behavior of the second-order spinhamiltonian parameters expected for simple models for crystal vibrations.
