Abstract

(LaY)₃(FeGa)₅O₁₂ (LaGaYIG) epitaxial film was grown on yttrium gadolinium garnet (YOG), and the properties of this film were investigated with emphasis on the temperature shift. It is found that the LaGaYIG/YOG film shows a parabolic temperature dependence of the perpendicular resonance field at room temperature and a ΔH value of 1-2 Oe at X-band. The performance of a magnetic forward volume wave (MSFVW) narrowband filter made from this material is also presented. This filter showed an extremely small center frequency change, within 11 MHz from 20°C to 60°C at 5.5 GHz
