- •
All the Zn ferrite films were single-phase with a spinel structure.
- •
The films annealed at 200 °C has a large Ms of 256 emu/cm3 and a high fr of 1.48 GHz.
- •
The film annealed at 200 °C have a large 渭′ of 16 and i渭″ of about 0 up to 500 MHz.
- •
It may be a good candidate for the film inductors operated at hundred MHz range.
