Apetrei R., Negrila C., Macovei D., Dascaleanu V., Teodorescu C.-M., Luca D., Alexandru Ioan Cuza University, RO

Ti1-xFexO2, 300 nm thin films with x ranging between 0.0 and 0.6, have been fabricated by RF magnetron sputtering. Specimen characterization was done by XPS, AFM, XRD,UV-Vis spectrometry, MOKE, and XANES/EXAFS techniques. The AFM and [...]

Pulsed laser co-deposition of titania with Fe: chemistry, local atomic structure, and light-dependent magnetic properties

Negrila C., Logofatu C., Socol G., Macovei D., Teodorescu C.-M., National Institute of Materials Physics, RO

Transition metal doped titania has been revealed as a promising diluted magnetic semiconductor. We report the synthesis of TiO2:Fe and of mixed Ti and Fe oxides by pulsed laser deposition. The obtained layers were analyzed [...]

Nanostructured thin layers of vanadium oxides doped with cobalt, prepared by pulsed laser ablation: structure, chemistry, morphology, and magnetism

Teodorescu C.-M., Socol G., Negrila C., Luca D., Macovei D., National Institute of Materials Physics, RO

The present study deals with cobalt-doped vanadium oxide thin layers prepared by pulsed laser ablation. Variation of the preparation parameters allows one to synthesize films with a variety of properties. The chemical composition of the [...]
