His ideas and input have aided me greatly in the exploration of ideas. I would like to thank my committee members, Dr. for their feedback and support. I would also like to the members of the CoFE group, whose input and development of the CoFE system have greatly aided the research in this area. In particular, I would like to thank Min Yang for her early work on distribution based algorithms. I ...

Incorporation of saccharin molecules has been studied during the galvanostatic deposition of 2.45 T CoFe alloys. The results indicate that the incorporation rate is strongly dependent on the concentration of saccharin in the plating solution. This dependence showed a pronounced maximum at Csac = 0.12 g L −1, which is a result with significant practical implications. A simple physical model was ...

In this paper, a remote O2 ion source is used for the formation of nano-oxide layers. The oxidation efficiency was measured in CoFe-oxide films, and a decrease of the oxide layer with the pan angle and the oxidation pressure is observed. For the same oxidation pressure, the oxidation efficiency depends on the O2 content in the Ar–O2 plasma. These results were applied in optimizing the fabricati...

Various iron group alloys have been electrodeposited and evaluated for properties including corrosion resistance, microstructure, electrical resistivity, magnetoresistance and other magnetic properties. Corrosion resistance depends on deposit composition and microstructure, which are controlled by solution composition and deposition variables. Maximum corrosion resistance was observed for 50Ni5...

SiO2-coated Cobalt Ferrite (CoFe2O4) nanoparticles were obtained by the hydrolysis of tetraethylorthosilicate in the presence of CoFe2O4 nanoparticles in co-precipitation. The effects of SiO2coating on the magnetic properties of CoFe2O4 nanoparticles were investigated. The structural, morphological and magne...
