Abstract
A fluxgate magnetometer is presented which exploits the magnetic field dependence to the stress-driven magnetisation fluctuations in magnetostrictive metallic glass ribbons. A magnetometer constructed with an unannealed ribbon, a piezoelectric ceramic driving element and a 100-turn pick-up coil exhibits a minimum detectable magnetic field of 15 nT/√Hz in the DC to 1 Hz bandwidth.Keywords
