VTechWorks staff will be away for the Memorial Day holiday on Monday, May 27, and will not be replying to requests at that time. Thank you for your patience.
Structural origin of the relaxor-to-normal ferroelectric transition in Pb(Mg1/3Nb2/3O3)-xPbTiO(3)
Abstract
A relaxor-to-normal, or micro-to-macrodomain, transition in Pb(Mg1/3Nb2/3O3)-xPbTiO(3), has been found under electric fields applied along [001] for x >= 0.24. It is shown that an intermediate tetragonal ferroelectric phase is important to the sharpness of this transition, as observed in its dielectric response. (c) 2006 American Institute of Physics.
