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