Abstract
100-300 nm thin Fe layers evaporated onto crystalline and amorphous Si or SiO2 substrates were irradiated, at 77 K, with 10(14)-10(16) Xe+-i ons/cm(2) at 450 keV beam energy. The magnetizations in the films were measured by means of Perturbed Angular Correlation (PAC) spectroscopy with implanted In-111 tracer ions, or the Magneto-Optic Kerr Effect ( MOKE). Upon ion implantation, dramatic changes of the magnetic anisotr opy were observed which are attributed to ion-beam enhanced lateral gr ain growth. Very little influence of the deposition parameters (type a nd cristallinity of substrate, evaporation rate) on the anisotropic ma gnetization was found. (C) 1998 Elsevier Science B.V.
