Effect of hydrostatic pressure on the dielectric response of Pb(Mg 1/3Nb2/3)O3 relaxor
Abstract
<p>The effect of hydrostatic pressure on the dielectric response of Pb(Mg <sub>1/3</sub>Nb<sub>2/3</sub>)O<sub>3</sub> relaxor single crystal was studied. An increase in the dispersion of the dielectric anomaly, characteristic of the relaxors, was observed: pressure-induced downward shift of the temperature Tm of permittivity maximum at 1kHz amounts to dT<sub>m</sub>/dp = - 3.8K/100MPa, whereas that measured at 1 MHz equals - 3.3 K/100MPa. Analysis of the dielectric response of the highly polarizable Pb(Mg<sub>1/3</sub>Nb<sub>2/3</sub>)O <sub>3</sub> shows that hydrostatic pressure results in a decrease of the correlation radius r<sub>c</sub> of polar nanodomains, as well as their activation energy.</p>
