Simulation of Magnetization Switching in Biaxial Single-Domain Ferromagnetic Particles
Xuekun Kou, M. A. Novotny, Per Arne Rikvold
The magnetization switching dynamics of biaxial single-domain homogeneous ferromagnetic particles, in which the two easy axes are perpendicular to each other, is simulated using a…
Test of the Kolmogorov-Johnson-Mehl-Avrami picture of metastable decay in a model with microscopic dynamics
Raphael A. Ramos, Per Arne Rikvold, M. A. Novotny
The Kolmogorov-Johnson-Mehl-Avrami (KJMA) theory for the time evolution of the order parameter in systems undergoing first-order phase transformations has been extended by Sekimoto…
Monolayer Solid Helium-4 Clusters on Graphite
M. E. Pierce, E. Manousakis
In order to resolve the controversy about the low density region of the phase diagram of the 4He monolayer on graphite, we have undertaken a path integral Monte Carlo study of the…
Slow Forcing in the Projective Dynamics Method
M. A. Novotny, M. Kolesik, P. A. Rikvold
We provide a proof that when there is no forcing the recently introduced projective dynamics Monte Carlo algorithm gives the exact lifetime of the metastable state, within statisti…
Computer Simulations of Thermal Switching in Small-grain Ferromagnets
M. A. Novotny, G. Brown, P. A. Rikvold
We present Monte Carlo and Langevin micromagnetic calculations to investigate thermal switching of single-domain ferromagnetic particles. For the Monte Carlo study we place particu…
Magnetic Particles
M. A. Novotny, P. A. Rikvold
We present an overview of the subject of Magnetic Particles, starting at a level suitable for advanced high-school students and ending at a level suitable for current practitioners…
Compensation Temperature of a Mixed Ising Ferrimagnetic Model in the Presence of External Magnetic Fields
G. M. Buendia, E. Machado, M. A. Novotny
The behavior of the compensation temperature of a mixed Ising ferrimagnetic system on a square lattice in which the two interpenetrating square sublattices have spins ($\pm 1/2…
Hard Simulation Problems in the Modeling of Magnetic Materials: Parallelization and Langevin Micromagnetics
G. Korniss, G. Brown, M. A. Novotny +1
We present recent results on two attempts at understanding and utilizing large-scale simulations of magnetic materials. In the first study we consider massively parallel implementa…
