Abstract
We report on a novel ferroelectric/gyromagnetic ferrite layered composite thin film with two degrees of tuning freedoms. The structure was prepared by layered growth of Y3Fe5O12(YIG) ferrite, LaNiO3(LNO) electrode and (1 0 0) orientated Pb0.4Sr0.6TiO3 (PST) ferroelectric films on Si substrates by RF magnetron sputtering. LNO not only exists as an electrode, but also provides a buffer layer for the orientation growth of PST film. The PST/YIG composite thin films exhibited large magnetic tunability of μr (92.1%@600 Oe), low FMR linewidth (ΔH) of 160.7 Oe@9.1 GHz and high electrical tunability (η) of 75%@360 kV/cm, which shows potential applications in magnetically and electrically tuning devices.
