The stochastic Langevin Landau-Lifshitz equation is usually utilized in micromagnetics formalism to account for thermal effects. Commonly, two different interpretations of the stochastic integrals can be made: Ito and Stratonovich. In this work, the Langevin-Landau-Lifshitz (LLL) equation is written

✦ Synopsis
It has been claimed recently that there is a contradiction between the Langevin and Ito theories
for nonlinear stochastic processes. We show that a simple reinterpretation reveals both these descriptions to be equivalent.
