Iron-garnet magnetic field sensors with 100 pT/√Hz noise-equivalent field



M. N. Deeter, Allen Rose, Gordon W. Day


The sensitivity of Faraday-effect sensors incorporating diamagnetically substituted yttrium iron garnet (YIG) is potentially much higher than of sensors employing pure YIG. Results of Faraday rotation linearity and sensitivity measurements are presented for gallium-substituted YIG. At 500 Hz, the noise equivalent magnetic field is approximately 100 pT/√Hz.
