Abstract
We characterize magnetic-field sensors based on the Faraday effect in ferromagnetic iron garnets in terms of their sensitivity, speed, and directionality. Signal-to-noise measurements at 80 Hz on small (typically 5 mm diameter × 3 mm long) samples of yttrium iron garnet (YIG) yield noise equivalent magnetic fields of 10 nT/√Hz. Frequency response measurements exhibit virtually flat response to approximately 700 MHz.Citation
