摘要

Single-phase Zn_(0.95-x)Cu_xLi_(0.05)O thin films have been prepared on Pt (1 1 1)/Ti/SiO_2 substrates by reactive magnetron sputtering method. The XRD, XPS and absorption measurements confirmed the polycrystalline nature of the films and the substitution of Zn~(2+) by Cu~(2+) ions. The sputtered Zn_(0.09)Cu_(0.05)Li_(0.05)O film shows multiferroic properties exhibiting a saturated ferroelectric loop with a remanent polarization of 6 μC/cm~2 and a saturated loop with a saturation magnetization of 0.43 μ_b/Cu at room temperature. The origins of the ferromagnetism and ferroelectricity in these films are discussed.
