Abstract
Sensors based on the Faraday effect can be configured to measure either magnetic fields or electric currents. Such sensors can be constructed without introducing conducting materials which are often undesirable. Presently, the most sensitive Faraday effect sensors employ ferrimagnetic iron garnets as the sensing elements. With these materials, we have demonstrated minimum detectable fields as low as 1 pT/Hz1⁄2 and currents as low as 200 nA/Hz1⁄2. This paper reviews these and other recent research results obtained at NIST and considers prospects for still further improvements in sensitivity and frequency response.Proceedings Title
