Introduction When high-frequency magnetic materials are evoked, garnets, ferrites, and ferromagnetic materials usually come to mind, these iron-based materials exhibit a relative permeability that differs from unity.[1-3] Yttrium iron garnet (Y3Fe5O12, YIG) which is a kind of typical garnet structure materials and gyromagnetic materials is widely used in microwave communication devices such as circulators, gyrators and phase shifters due to its high resistance, small anisotropy constant, narrow ferromagnetic resonance, line width and low dielectric loss in microwave regions. [4] In recent years, with the rapid development of electronic communications technology, YIG material has been widely used in mobile communication and antenna radar system.
It is significant in practical application to tune the electromagnetic parameters of materials.

Several pyrochlore and perovskite materials have shown promising physical and thermal properties for use as complementary upper layer of YSZ in the FGM TBC system.
These materials exhibit lower thermal conductivity and higher thermal stability than YSZ [2,5,6].
To remedy this shortcoming, the candidate materials were tried as complementary topcoat for YSZ in double layer systems.
