Finite Difference Method for the Landau-Lifshitz Equation
이영백,남원창,조민형 한국물리학회 2008 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.53 No.3
A numerical approach, based on a nite difference method and a successive over relaxation (SOR) method, is presented for the Landau-Lifshitz or the Landau-Lifshitz-Gilbert equation for the study on the dynamics of magnetization. One- and two-dimensional formula for the discretized Landau- Lifshitz equation with an exact solution are described and numerically solved using the Gauss-Seidel and the SOR methods. The numerical errors are compared for both methods and the optimum relaxation factor, !, for the SOR method is numerically found.
