Spinel ferrite/metal composite thin films of MFe2O4/Fe (M ) Zn, Mg) with controlled grain sizes and shape were directly fabricated by a soft solution-processing route that involved the liquid-solid interfacial hydrothermal reaction of an Fe substrate with metal ions M2+ (M ) Zn, Mg) in ammonia solution at lower temperatures (
