Abstract
The stability of a fiber-optic magnetometer employing metallic glass ribbons was examined over a period of more than 10 h. The magnetometer can be operated either in the open magnetic loop or the closed magnetic loop configuration. The short-term minimum detectable magnetic field for ≈ 10 cm of sensor fiber length was less than 2 gamma in the dc to 1-Hz bandwidth. Long-term stability of approximately 10 gamma was achieved in the closed magnetic loop configuration.
