Two-dimensional and three-dimensional magnetism in ultrathin epitaxial rare-earth metal films

This thesis reports the investigation of the magnetic behavior of ultrathin epitaxial films of the heavy rare-earth elements; Gd, Er, and Dy, grown with the technique of Molecular Beam Epitaxy (MBE). By employing advanced film fabrication techniques, each magnetic rare-earth element layer, between 0.1 and 10 atomic layers thick and magnetically separated from one another by thick spacers, is grown in layer-by-layer growth mode to insure high crystal quality. Magnetization of the resulting films is measured to identify the spin structures and the magnetic phases. The localized 4f spins in the rare-earth layers and complete interlayer magnetic separation give the present approach a unique advantage over the previously used experimental methods.
