Step Position Distributions and the Pairwise Einstein Model for Steps on Crystal Surfaces (2003)

Benson, Amber N., Richards, Howard L., Einstein, T. L.

The Pairwise Einstein Model (PEM) of steps not only justifies the use of the Generalized Wigner Distribution (GWD) for Terrace Width Distributions (TWDs), it also predicts a specific form for the...

Terrace-Width Distributions and Step-Step Repulsions on Vicinal Surfaces: Symmetries, Scaling, Simplifications, Subtleties, and Schr\"odinger (2000)

Einstein, T. L., Richards, Howard L., Cohen, Saul D., Pierre-Louis, O.

For more than three decades, measurement of terrace width distributions (TWDs) of vicinal crystal surfaces have been recognized as arguably the best way to determine the dimensionless strength...

Beyond the Wigner Distribution: Schr{\"o}dinger Equations and Terrace Width Distributions (2000)

Richards, Howard L., Einstein, T. L.

The so-called generalized Wigner distribution has earlier been shown to be an excellent approximation for the terrace width distribution (TWD) of vicinal surfaces characterized by step-step...

Extraction of Step-Repulsion Strengths from Terrace Width Distributions: Statistical and Analytic Considerations (1999)

Richards, Howard L., Cohen, Saul D., Einstein, T. L., Giesen, M.

Recently it has been recognized that the so-called generalized Wigner distribution may provide at least as good a description of terrace width distributions (TWDs) on vicinal surfaces as the standard...

Extrapolation-CAM Theory for Critical Exponents (1997)

Richards, Howard L., Hatano, Naomichi, Novotny, M. A.

By intentionally underestimating the rate of convergence of exact-diagonalization values for the mass or energy gaps of finite systems, we form families of sequences of gap estimates. The gap...

Effects of boundary conditions on magnetization switching in kinetic Ising models of nanoscale ferromagnets (1996)

Richards, Howard L., Kolesik, M., Lindgard, Per-Anker, Rikvold, Per Arne, Novotny, M. A.

Magnetization switching in highly anisotropic single-domain ferromagnets has been previously shown to be qualitatively described by the droplet theory of metastable decay and simulations of...

Analytical and computational study of magnetization switching in kinetic Ising systems with demagnetizing fields (1995)

Richards, Howard L., Novotny, Mark A., Rikvold, Per Arne

An important aspect of real ferromagnetic particles is the demagnetizing field resulting from magnetostatic dipole-dipole interaction, which causes large particles to break up into domains....

Kinetic Ising Systems as Models of Magnetization Switching in Submicron Ferromagnets (1995)

Richards, Howard L., Sides, Scott W., Novotny, Mark A., Rikvold, Per Arne

Recently experimental techniques, such as magnetic force microscopy (MFM), have enabled the magnetic state of individual sub-micron particles to be resolved. Motivated by these experimental...

Magnetization switching in nanoscale ferromagnetic grains: description by a kinetic Ising model (1994)

Richards, Howard L., Sides, Scott W., Novotny, M. A., Rikvold, Per Arne

The magnetic relaxation of ferromagnetic powders has been studied for many years, largely due to its importance to recording technologies. However, only recently have experiments been performed that...

A Numerical Transfer-Matrix Study of Surface-Tension Anisotropy in Ising Models on Square and Cubic Lattices (1993)

Richards, Howard L., Novotny, M. A., Rikvold, Per Arne

We compute by numerical transfer-matrix methods the surface free energy $\tau(T),$ the surface stiffness coefficient $\kappa(T),$ and the single-step free energy $s(T)$ for Ising ferromagnets with...
