The responsitivity and sensitivity of fiber interferometric sensors based on magnetostrictive transducers consisting of up to 25 m of annealed metallic glass wire are reported. The frequency and temperature range of these sensors is examined both theoretically and experimentally. The performance of these sensors is acceptable for the transient electromagnetic method of geomagnetic surveying
