Resolution-dependent mechanisms for bimodal switching-time distributions in simulated Fe nanopillars
S. H. Thompson, G. Brown, A. Kuhnle +2
We study the magnetization-switching statistics following reversal of the applied field for three separate computational models representing the same physical system, an iron nanop…
Calculated Magnetic Exchange Interactions in High-Temeprature Superconductors
Xiangang Wan, Thomas A. Maier, Sergej Y. Savrasov
Using a first principles linear response approach, we study the magnetic exchange interactions J for a series of superconducting cuprates. We reproduce the observed spin-wave dispe…
Self-healing diffusion quantum Monte Carlo algorithms: methods for direct reduction of the fermion sign error in electronic structure calculations
Fernando A. Reboredo, Randolph Q. Hood, Paul R. C. Kent
We develop a formalism and present an algorithm for optimization of the trial wave-function used in fixed-node diffusion quantum Monte Carlo (DMC) methods. We take advantage of a b…
Surface Effect on Domain Wall Width in Ferroelectrics
Eugene A. Eliseev, Anna N. Morozovska, Sergei V. Kalinin +5
We study the effect of depolarization field related with inhomogeneous polarization distribution, strain and surface energy parameters on a domain wall profile near the surface of…
Effect of the Intrinsic Width on the Piezoelectric Force Microscopy of a Single Ferroelectric Domain Wall
Anna N. Morozovska, Eugene A. Eliseev, George S. Svechnikov +2
Intrinsic domain wall width is a fundamental parameter that reflects bulk ferroelectric properties and governs the performance of ferroelectric memory devices. We present closed-fo…
Imaging Mechanism of Piezoresponse Force Microscopy in Capacitor Structures
Sergei V. Kalinin, Brian J. Rodriguez, Seung-Hyun Kim +3
The image formation mechanism in Piezoresponse Force Microscopy (PFM) of capacitor structures is analyzed. We demonstrate that the spatial resolution is a bilinear function of film…
