Nature of the Atomic Structure Underlying the Vortex Polarization Domains in Hexagonal RMnO3

ORAL

Abstract

Hexagonal phase RMnO3 systems exhibit polarization domains with complex vortex pattern with density depending on the cooling rate from the high temperature paraelectric phase. Structural measurements are used to probe the structure on length scales commensurate with the variations in polarization. Structural measurements reveal variations on the lenghtscale of the changes in polarization.
