摘要：
It is shown that, in magnetomodulation sensors of a weak magnetic field with amorphous ferromagnetic cores, the signals of an amplitude-modulated high-frequency magnetic field, the frequency of which lies above the passband of the sensors, are partially transferred to a low-frequency band. Part of the high-frequency magnetic noise is redistributed by the sensor into the low-frequency band, which contributes to the observed dependence of the amplitude of 1/f noise.
