Scaling of the Coercive Field with Thickness in Thin-Film Ferroelectrics
P. Chandra, M. Dawber, P. B. Littlewood +1
Motivated by the observed thickness-scaling of the coercive field in ferroelectric films over five decades, we develop a statistical approach towards understanding the conceptual u…

Efficient Switching and Domain Interlocking Observed in Polyaxial Ferroelectrics
A. Krishnan, M. M. J. Treacy, M. E. Bisher +2
We present in-situ transmission electron microscopy observations of domain wall motion in thin freestanding potassium niobate single-crystals. We observe that not all domains of a…

Spin Models on Non-Euclidean Hyperlattices: Griffiths Phases without Extrinsic Disorder
J. C. Angles d'Auriac, R. Melin, P. Chandra +1
We study short-range ferromagnetic models residing on planar manifolds with global negative curvature. We show that the local metric properties of the embedding surface induce drop…
