A compact ultrahigh-vacuum chamber, specially designed to allow in situ Brillouin light-scattering ~BLS! and surface magneto-optical Kerr-effect measurements has been set up. Experimental results relative to both the structure and the magnetic properties of ultrathin Fe films grown by e-beam evaporation on a Cu~110! single crystal are presented. Low-energy electron diffraction patterns account for epitaxial growth of fcc Fe~110! up to 4-6 Å, followed by a transition to a more disordered state, consisting of bcc Fe domains. The BLS analysis enabled us to study the dependence of the spin-wave frequency on the angle of incidence of light, on the intensity of the magnetic field, and on its direction on the surface plane.

Abstract
A compact ultrahigh-vacuum chamber, specially designed to allow in situ Brillouin light-scattering ~BLS! and surface magneto-optical Kerr-effect measurements has been set up. Experimental results relative to both the structure and the magnetic properties of ultrathin Fe films grown by e-beam evaporation on a Cu~110! single crystal are presented. Low-energy electron diffraction patterns account for epitaxial growth of fcc Fe~110! up to 4-6 Å, followed by a transition to a more disordered state, consisting of bcc Fe domains. The BLS analysis enabled us to study the dependence of the spin-wave frequency on the angle of incidence of light, on the intensity of the magnetic field, and on its direction on the surface plane.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
