Exchange coupling in ultrathin Fe(8 A)/[Cu/Tb (12 A) film structure has been studied. The film samples were prepared on Si substrates by electron-beam evaporation in an ultrahigh vacuum system having a background pressure ...

Bilayer films Fe/Tb (Tb on Fe) having sharp and Tb/Fe (Fe on Tb) having rough interface were prepared by molecular beam epitaxy to study interlayer magnetic coupling. Magnetic properties of these bilayers were characterized ...
