Abstract:
Surface acoustic phonon modes in pelletized polycrystalline Pb(Mg1∕3Nb2∕3)O3 are investigated in the frequency range from 5to40cm−1 at various temperatures from 25to550°C. These spectra support the hypothesis of the core-shell nanoclusters with 1:1 ordered, negatively charged nanocore surrounded by the charge compensating positively charged disordered nanoshell. These surface acoustic modes exist even up to 550°C revealing the existence of the charged core-shell nanoclusters which is well beyond the dissolution temperature of the polar clusters in the material.
