SUMMARY:Nanodomains in Ferroelectrics and Magnetoelectrics - J. F. Scott\,
  Cavendish Laboratory\, Cambridge
DTSTART:20100421T101500Z

CONTACT:Michael Sutherland
DESCRIPTION:I will present a review of recent theory and experiment concer
 ning nanodomains.  For many years domains in ferroelectrics were thought t
 o be rectilinear\, with for example\, 180 and 90 degree domains in tetrago
 nal crystals\, 109 and 71 degree domains in rhombohedral crystals.  Recent
 ly\, however\, experiments have revealed circular closure or vortex domain
 s and toroidal domains (see attached figure).  A brief history\, starting 
 with Ginzburg in 1984 and concluding with work this month by Igor Lukyanch
 uk (Amiens) and the present author will be given.
