Field sweep rate dependence of magnetic domain patterns: Numerical simulations for a simple Ising-like model
Abstract
We study magnetic domain patterns in ferromagnetic thin films by numerical simulations for a simple Ising-like model. Magnetic domain patterns after quench demonstrate various types of patterns depending on the field sweep rate and parameters of the model. How the domain patterns are formed is shown with use of the number of domains, the domain area, and domain area distributions as well as snapshots of domain patterns. Considering the proper time scale of the system, we propose a criterion for the structure of domain patterns.
