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…
Glassy Behavior in the Ferromagnetic Ising Model on a Cayley Tree
R. Melin, J. C. Angles d'Auriac, P. Chandra +1
We present a detailed study of the nearest-neighbor ferromagnetic Ising model on a Cayley tree. In the limit of zero field, the system displays glassy behavior below a crossover te…
