Abstract
Zinc oxide based material systems are considered as promising candidate for spintronic devices if it could be coupled in heterostructure with a suitable ferromagnetic material. We synthesized Zn, Mn and Co substituted iron oxide powders and thin films using solution-based approaches. Structural properties of these materials were studied by X-ray diffraction, FT-IR and closed cycle SQUID for magnetic characterization. These studies indicates that Zn1âxCoxFe2O4, Mn0.5Zn0.5Fe2O4 and CoFe2O4 exhibited ferrimagnetic and superparamagnetic behavior, respectively, at room temperature. Superparamagnetic behavior in Mn0.5Zn0.5Fe2O4 and CoFe2O4 is attributed to the extremely small crystal size.
