Abstract :
A YIG film having a small frequency-temperature dependence with a low ΔH has been investigated both theoretically and experimentally. It is found that the frequency-temperature characteristics of a low-loss Bi,Ga substituted YIG film epitaxially grown on a (111) oriented GGG substrate with a proper growth-induced anisotropy magnetic field are better than those of a YIG sphere. A MSFVW chip resonator made from this film is also demonstrated
