Microscopic Spin Wave Study of the Co/Cu(100) Epitaxial Monolayer
Recent progress1 in the preparation and investigation of high quality epitaxial monolayers (ML) has renewed the interest for two-dimensional (2D) magnetism. In particular, the temperature dependence of the magnetization of the Co/Cu(100) monolayer was measured with great accuracy using spin-polarized low-energy electron diffraction (SPLEED), and magneto-optical Kerr effect.2 The field dependence of the magnon energy gap was detected by means of light scattering.2
