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
