Notes:
We present a novel approach to the calculation of the spin structures and magnetic anisotropies in crystals and thin films. Our technique is based on self-consistent real-space recursion calculations on a tight-binding linear muffin-tin orbital (TB LMTO) Hubbard Hamiltonian including spin–orbit coupling and allowing for arbitary orientations of the local spin-quantization axes. It allows one to scan the magnetic energy continuously as a function of the orientation of the magnetic moment and thus to avoid the computational problems that plague other techniques. Applications are presented for bulk iron and for thin Fe overlayers on Cu (111) and Cu (100) substrates. For monolayer coverage, we predict a perpendicular direction of the magnetic moment for Fe/Cu(100) an in-plane orientation of the spins for Fe/Cu(111), with anisotropies of the order of 1–2 meV. For Fe/Cu(100) we present a detailed investigation of the variation of the spin structures and of the change from perpedicular to in-plane anisotropy with increasing thickness of the Fe films. © 1996 American Institute of Physics.
