Abstract
We present frequency-tunable, photolithography compatible superconducting microwave resonators designed for integration with electro-optic devices. We demonstrate >500 MHz of tuning with a bulk permanent magnet and > 1 00 MHz of tuning with planar coils under moderate (<5 mT) magnetic fields.
