Title: Numerical integration of the stochastic Landau-Lifshitz-Gilbert equation in generic time-discretization schemes. Author: Romá F, Cugliandolo LF, Lozano GS. Journal: Phys Rev E Stat Nonlin Soft Matter Phys; 2014 Aug; 90(2):023203. PubMed ID: 25215839. Abstract: We introduce a numerical method to integrate the stochastic Landau-Lifshitz-Gilbert equation in spherical coordinates for generic discretization schemes. This method conserves the magnetization modulus and ensures the approach to equilibrium under the expected conditions. We test the algorithm on a benchmark problem: the dynamics of a uniformly magnetized ellipsoid. We investigate the influence of various parameters, and in particular, we analyze the efficiency of the numerical integration, in terms of the number of steps needed to reach a chosen long time with a given accuracy.[Abstract] [Full Text] [Related] [New Search]
