We compute by numerical transfer-matrix methods the surface free energy τ (T), the surface stiffness coefficient κ(T), and the single-step free energy s(T) for Ising ferromagnets with (∞×L) square-lattice and (∞×L×M) cubic-lattice geometries, into which an interface is introduced by imposing antiperiodic or plus/minus boundary conditions in one transverse direction. The surface tension σ(θ, T) per unit length of interface projected in the longitudinal direction defines τ (T) and κ(T) for… CONTINUE READING
