Sequential pulsed laser deposition of CoO and CeO 2 at 650 °C under vacuum leads to the formation of a slanted Co nanowires assembly embedded in CeO 2/SrTiO 3(0 0 1) epilayers. High temperature magneto-optical Faraday measurements were performed, which revealed a Faraday ellipticity of 1.3° at a wavelength of 450 nm for 300 nm thick samples and which allowed to access the magnetic properties. From the analysis of the coercivity dependence on temperature, it is shown that the magnetic anisotropy of the slanted Co nanowires is dominated by shape anisotropy and that their magnetization reversal is localized. © 2011 Elsevier B.V.
