High-temperature dielectric response of ferroelectric relaxors

It has long been considered that polar nanoregions in relaxors form at Burns temperature T d - 600K. High-temperature dielectric investigations of Pb(Mg 1/3 Nb 2/3 ) O 3 (PMN) single crystal, PMN-PbTiO 3 ceramics, and (Pb,La) (Zr,Ti)O 3 ceramics reveal, however, that dielectric dispersion, detected...
