Abstract
A low-frequency magnetometer has been constructed by interfacing a transversely field-annealed amorphous metal ribbon to a resonating piezoelectric ceramic plate. Power spectrum measurements from 20 mHz to 1.0 Hz demonstrate a minimum detectable field of 8.7 pT/√Hz at 1.0 Hz with an approximate 1/f rise in the noise floor.Keywords
