Magneto-optical properties of Co coated ZnO nanorods

Popis výsledku v původním jazyce

ZnO NRs array were fabricated by electro-chemical deposition. After electro-chemical deposition, Co layers were coated on the ZnO NRs array also using sputtering. As the Co capping, band tailing becomes evident in the data with the onset of absorption at lower energy.nThe absorption at low energy in Co capped films may indicate the Co derived states near the band edge 3.4eV. A sizeable magnetoabsorption change can be observed after the band tail at room temperature under magnetic field∼ 0.8 T. A ferromagnetic interfacial spin-polarized semiconductor band of Co-coated ZnO NRs is also observed by measuring magnetic circular dichroism effect. A phenomenological model related to magnetic field-dependent spinnsplitting band structures near the Co/ZnO interfaces due to charge transfer between the Co d orbit and the defect-related band has been proposed to describe the observed magneto-optical properties.
