Abstract
Recent research demonstrating greater performance of Faraday effect sensors based on iron garnet crystals is described. Bulk crystals are coupled to high-permeability flux concentrators, resulting in an increase in sensitivity of at least two orders of magnitude. Iron garnet films with perpendicular magnetic anisotropy and exploited in an optical waveguide geometry exhibit greater frequency response than bulk crystals. These films also exhibit larger values of saturation Faraday rotation and ideally should exhibit no hysteresis.Proceedings Title
