Abstract

The Letter demonstrates that the sensitivity of magneto-optic magnetic field sensors employing iron garnets can be increased by approximately two orders of magnitude by applying flux concentration. A minimum detectable field of 1.4 pT/√(Hz) was measured when a cylindrical gallium substituted yttrium iron garnet crystal was combined with two conically tapered nickel-zinc ferrite cylinders.
