Landau–Lifshitz model
From Wikipedia, the free encyclopedia
For another Landau–Lifshitz equation describing magnetism, see Landau–Lifshitz–Gilbert equation.
In solid-state physics, the Landau–Lifshitz equation (LLE), named for Lev Landau and Evgeny Lifshitz, is a partial differential equation describing time evolution of magnetism in solids, depending on 1 time variable and 1, 2, or 3 space variables.
