Functional properties of nickel cobalt oxide thin films
F Iacomi, G Calin, C Scarlat, M Irimia, C Doroftei… - Thin Solid Films, 2011 - Elsevier
Cobalt–nickel oxide films of known stoichiometry (x= Ni/(Co+ Ni)= 0.30–0.63) were
deposited on glass slides by using a spin-coating method and were UV irradiated for 2h.
The structure and morphology of thin films evidenced nanocrystalline spinel structures. Thin
films with x= 0.63–0.5 have a mixed phase structure and good sensing properties for
ethanol. Thin films with x= 0.30–0.40 have a single spinel phase, are ferrimagnetic and
highly conductive at 300K and have magnetoresistance ratios of 5–8%. Four-probe …
