Reversal Modes of Simulated Iron Nanopillars in an Obliquely Oriented Field
S. H. Thompson, G. Brown, P. A. Rikvold
Stochastic micromagnetic simulations are employed to study switching in three-dimensional magnetic nanopillars exposed to highly misaligned fields. The switching appears to proceed…
FORC Analysis of homogeneous nucleation in the two-dimensional kinetic Ising model
D. T. Robb, M. A. Novotny, P. A. Rikvold
The first-order reversal curve (FORC) method is applied to the two-dimensional kinetic Ising model. For the system size and magnetic field chosen, the system reverses by the homoge…
Projective Dynamics in Realistic Models of Nanomagnets
S. H. Thompson, G. Brown, P. A. Rikvold
The free-energy extrema governing the magnetization-reversal process for a model of an iron nanopillar are investigated using the projective dynamics method. Since the time evoluti…
Low-temperature nucleation in a kinetic Ising model under different stochastic dynamics with local energy barriers
Gloria M. Buendia, Per Arne Rikvold, Kyungwha Park +1
Using both analytical and simulational methods, we study low-temperature nucleation rates in kinetic Ising lattice-gas models that evolve under two different Arrhenius dynamics tha…
Low-temperature nucleation in a kinetic Ising model with soft stochastic dynamics
Kyungwha Park, Per Arne Rikvold, Gloria M. Buendia +1
We study low-temperature nucleation in kinetic Ising models by analytical and simulational methods, confirming the general result for the average metastable lifetime, <tau> = A*exp…
Projective Dynamics Analysis of Magnetization Reversal
G. Brown, M. A. Novotny, P. A. Rikvold
The computational Projective Dynamics method is used to analyze simulations of magnetization reversal in nanoscale magnetic pillars. It is shown that this method can be used to det…
