Fig. 4: The manipulation of vortex chirality by bi-domain arrangements.
From: Phase-field simulations of vortex chirality manipulation in ferroelectric thin films
The bi-domain arrangements are separated by 180° and 109° DWs oriented along the y axis: a Initial R3+|R3− polarization arrangement and LH chiral vortex. b Initial R3−|R3+ polarization arrangement and RH chiral vortex. c Initial R3+|R2− polarization arrangement and LH chiral vortex. d Initial R2−|R3+ polarization arrangement and LH vortex. The bi-domain arrangements are separated by 180° and 109° DWs oriented along the x axis. e Initial R3+/R3− polarization arrangement and RH vortex. f Initial R3−/R3+ polarization arrangement and LH vortex. g Initial R3+/R2− polarization arrangement and RH vortex. h Initial R2−/R3+ polarization arrangement and LH vortex.
