- Abstract
- Solving the stochastic Landau-Lifshitz-Gilbert equation numerically, we investigate the attempt frequency of magnetization in
synthetic antiferromagnet (SyAF). The attempt frequency is estimated while varying the uniaxial anisotropy constant, the energy
barrier and the geometry of a magnetic layer. It is found that the attempt frequency is decreased for the same magnetic volume by
increasing the asymmetry of the geometry in the high damping region. Also, even for a constant height of energy barrier, the attempt
frequency can vary dramatically with uniaxial anisotropy constant.
