Magnetron sputtering is a widely used physical vapor deposition technique for deposition and formation of nanocatalyst thin films and clusters. Nevertheless, so far only few studies investigated this formation process at the fundamental level. We here review atomic scale molecular dynamics simulations aimed at elucidating the nanocatalyst growth process through magnetron sputtering. We first in...
In bulk FeTi alloys prepared by facing target type sputtering, an amorphous phase was obtained between 25 and 75 at% Ti. These alloys are weak itinerant electron ferromagnets and the Curie temperature decreases with increasing Ti concentration and becomes zero at about 60 at% Ti.
In this paper we study the feasibility of representing the optical properties of ultrathin gold films by effective medium theories. Gold films with mass thicknesses in the range of 1.4 to 9.2 nm were deposited by DC magnetron sputtering onto non-heated glass substrates. Optical measurements in the range 0.25 to 2μm were carried out by spectroscopic ellipsometry, and the effective complex dielec...
We report the experimental observation of room-temperature perpendicular magnetic anisotropy in Ni/Pt multilayers having 7–26 Å Ni and 2.3–4.6 Å Pt layer thicknesses, prepared by dc magnetron sputtering on glass substrates at 7 mTorr Ar sputtering pressure. Perpendicular magnetic anisotropy was found to be sensitively dependent on both Niand Pt-layer thicknesses, and a maximum anisotropy energy...
