Ba deposition and oxidation on theta-[Al.sub.2][O.sub.3]NiAl(100) ultrathin films. Part I: Anaerobic deposition conditions

Article Abstract:

Room-temperature Ba deposition on an oxygen-terminated theta-[Al.sub.2][O.sub.3]/NiAl(100) ultrathin film substrate under high vacuum (UHV) conditions is analyzed by using various spectroscope techniques. The results have shown that at room temperature Ba grows in a layer-by-layer fashion for the first two layers, and Ba is partially oxidized.

Ordered patterning of nanometric rings of single molecule magnets on polymers by lithographic control of demixing

Article Abstract:

A new application of the demixing process combined with chemical patterning of a binary polymer/solute mixture for the fabrication is described. Mn12 clusters are used as representative material and Mn12 patterned film spontaneously evolve in a spatially correlated pattern of nanorings and then this process is controlled for nanopatterning.
