The structural and magnetic properties of thin Co films grown on Au(111) substrates are investigated using ab initio local-spin-density calculations in the generalized gradient approximation. It is shown that a large lattice intermismatch between Co and Au(111) leads to a strong contraction of the interlayer distances within the Co layer, which adopts either the hexagonal close-packed (α-phase) or...
Numerical results of a new (interface-rescaling) theory of normal excitations in a triple-layer film are reported. The film is modelled by three one dimensional finite chains coupled together; the coupling across the interface is properly taken into account. The formation process of the film energy spectrum as a result of interface (i.e. inter-chain) coupling is studied, and the exact conditions for...
