1 | Mattis, Daniel C. | Improved Landau-Ginzburg equation near surfaces of solids | We study the order parameter near the surface for an Ising model. Applications to the lattice gas, alloy problem, and ferromagnetism are noted. Away from Tc our equations differ from the Landau-Ginzburg results due to an additional nonlinear, term which can substantially affect the order parameter... | Landau-Ginzburg equation; Boundary conditions | 1980-12 |
