Magnetic properties of Co-doped TiO2 anatase nanopowders
L. C. J. Pereira, M. R. Nunes, O. C. Monteiro +1
This letter reports on the magnetic properties of Ti1-xCoxO2 anatase phase nanopowders with different Co contents. It is shown that oxygen vacancies play a fundamental role in prom…
CVD of CrO2: towards a lower temperature deposition process
P. M. Sousa, S. A. Dias, A. J. Silvestre +5
We report on the synthesis of highly oriented a-axis CrO2 films onto (0001) sapphire by atmospheric pressure CVD from CrO3 precursor, at growth temperatures down to 330 degree Cels…
CVD of CrO2 Thin Films: Influence of the Deposition Parameters on their Structural and Magnetic Properties
A. F. Mota, A. J. Silvestre, P. M. Sousa +3
This work reports on the synthesis of CrO2 thin films by atmospheric pressure CVD using chromium trioxide (CrO3) and oxygen. Highly oriented (100) CrO2 films containing highly orie…
KrF pulsed laser deposition of chromium oxide thin films from Cr8O21 targets
N. Popovici, M. L. Parames, R. C. da Silva +4
Chromium oxides, CrxOy, are of great interest due to the wide variety of their technological applications. Among them, CrO2 has been extensively investigated in recent years becaus…
Morphological and Structural Characterization of Cro2/Cr2o3 Films Grown by Laser-CVD
P. M. Sousa, A. J. Silvestre, N. Popovici1 +1
This work reports on the synthesis of chromium (III, IV) oxides films by KrF laser-assisted CVD. Films were deposited onto sapphire substrates at room temperature by photodissociat…
TiN Films Deposited by Laser CVD: A Growth Kinetics Study
A. J. Silvestre, O. Conde
Results on the chemical composition, structure and growth kinetics of titanium nitride (TiN) films deposited on mild steel substrates by pyrolytic laser-induced chemical vapour dep…
