The Effect of Damping Coefficient on the Saturated Magnetization Field and Configuration of Domain Structures

ZHAO Ying-hua,MA Xing-qiao,WANG Zi-jun(Department of Physics,Beijing University of Science and Technology,Beijing 100083,China)  
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.
