The Significance of the Burns Temperature in Relaxor PMN
S. A. Prosandeev, S. B. Vakhrushev, N. M. Okuneva +4
We suggest considering the Burns temperature in lead containing relaxor ferroelectrics as the temperature, at which Pb becomes off-center and nearly randomly occupies positions aro…
Experimental and theoretical study of the influence of disorder on diffuse first-order phase transitions: NaNbO3: Gd and KTaO3: Li as examples
M. S. Prosandeeva, S. I. Rayevskaya, S. A. Prosandeev +2
We consider consequences of local disorder in systems experiencing first order phase transitions. Such systems can be of rather different nature. For example, manganates showing gi…
Diffuse first-order phase transition in NaNbO:Gd (a report)
I. P. Raevski, S. I. Raevskaya, S. A. Prosandeev +3
Dielectric permittivity measurements show that (1-x)NaNbO3-(x)Gd1/3NbO3 crystals, at , exhibit a first order phase transition near 150 C which is diffuse over a wide temper…
Random-Site Cation Ordering and Dielectric Properties of PbMg1/3Nb2/3o3-PbSc1/2Nb1/2o3
I. P. Raevski, S. A. Prosandeev, S. M. Emelyanov +8
(1-x)PbMg1/3Nb2/3O3-(x)PbSc1/2Nb1/2O3 (PMN-PSN) solid solution crystals have been grown by the flux method in the whole concentration range. X-ray supercell reflections due to B-ca…
Comparative Dielectric Behavior of PbFeTaO and NaNbO:Gd Relaxor-Like Crystals
I. P. Raevski, S. A. Prosandeev, U. Waghmare +3
Experimental data obtained for PbFeTaO (PFT) and NaNbO: Gd (NaNbGd) single crystals show a diffused dielectric permittivity peak that is inherent to…
