我们报告了一种新型的铁电/旋磁铁氧体层状复合薄膜与两个自由度的调谐。采用射频磁控溅射法在Si基片上分层生长Y3 Fe 5 O 12(YIG)铁氧体、LaNiO 3(LNO)电极和(1 0 0)取向的Pb 0. 4Sr 0. 6 TiO 3(PST)铁电薄膜。LNO不仅作为电极存在,而且为PST薄膜的取向生长提供了缓冲层。PST/YIG复合薄膜在600 Oe时的磁调谐率为92.1%,9.1 GHz时的FMR线宽为160.7 Oe,在360 kV/cm时的电调谐率为75%。
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.
