The Transition State in Magnetization Reversal
G. Brown, M. A. Novotny, P. A. Rikvold
We consider a magnet with uniaxial anisotropy in an external magnetic field along the anisotropy direction, but with a field magnitude smaller than the coercive field. There are th…
Extreme Long-time Dynamic Monte Carlo Simulations
Miroslav Kolesik, M. A. Novotny, Per Arne Rikvold
We study the extreme long-time behavior of the metastable phase of the three-dimensional Ising model with Glauber dynamics in an applied magnetic field and at a temperature below t…
Scaling analysis of a divergent prefactor in the metastable lifetime of a square-lattice Ising ferromagnet at low temperatures
Kyungwha Park, M. A. Novotny, P. A. Rikvold
We examine a square-lattice nearest-neighbor Ising quantum ferromagnet coupled to -dimensional phonon baths. Using the density-matrix equation, we calculate the transition rates…
Role of dipolar and exchange interactions in the positions and widths of EPR transitions for the single-molecule magnets Fe8 and Mn12
Kyungwha Park, M. A. Novotny, N. S. Dalal +2
We examine quantitatively the temperature dependence of the linewidths and line shifts in electron paramagnetic resonance experiments on single crystals of the single-molecule magn…
