This work was supported by MEC through projects MAT2006-01259 and MAT2009-07882.Exchange anisotropy has been observed and investigated in single-crystalline CuO nanowires grown by thermal oxidation of Cu. The exchange bias field decreases by increasing temperature and can be tuned by the strength of the cooling field. A training effect has also been observed. The obtained results can be understood in terms of a phenomenological core-shell model, where the core of the CuO nanowire shows antiferromagnetic behavior and the surrounding shell behaves as a spin glass-like system due to uncompensated surface spins.engjournal articlehttp://dx.doi.org/10.1063/1.3428658http://scitation.aip.orgopen access538.9NanostructuresFísica de materiales
