摘要：
A new type of fluxgate magnetometer is presented that makes use of the hysteretic non-linearity of the transfer characteristic of a fluxgate probe which operates in parametric resonance regime. A description if given of both the mathematical model of the fluxgate operation and the double-pumping magnetometer which uses two fields of different frequencies: an excitation field which determines, under certain conditions, the parametric generation of high amplitude second harmonic oscillations, and another field of lower frequency, which modifies the phase and amplitude of the second harmonic parametric oscillations.
