| Abstract: | The paper simulated the magnetic domain structures of single crystal Gd 2.34Tb 0.66Fe 5O12 with phase field method and worked out the Landau-Lifshitz-Gilbert equation by means of parallel method,fast Fourie transformation and Gauss-Sidel method in order to describe the process of magnetization.It was found that the damping coefficient had an effect on the pattern of magnetic domain structures when the two-dimensional simulation system was used. |
