摘要：
It is shown that an autoparametric magnetic-induction sensor with cores made of amorphous ferromagnetic alloy with compensated longitudinal magnetostriction, under conditions of low external magnetic noise at frequencies higher than 1 Hz, is capable of recording a magnetic field of amplitude 0.3 pT with a maximum noise density at frequencies above 3 Hz, not exceeding 0.2⋅pT·Hz−1/2.
