- •
The BMN films were prepared by PLD at different oxygen pressure.
- •
The films deposited at 10 Pa have a medium tunability of 22.1%.
- •
The films deposited at 10 Pa have the minimum degree of preferred orientation.
- •
Oxygen pressure dependence of preferred orientation was discussed.
- •
Preferred orientation dependence of permittivity and tangent loss was discussed.
