AB - It has been noted that the main part of the magnetic noise in flux gates and magnetomodulation sensors with cores of amorphous ferromagnetic alloys obtained by the rapid quenching method arises as a result of strong magnetoelastic interaction. Recent advances in lowering the sensitivity threshold of active weak magnetic field sensors based on amorphous ferromagnetics are considered. An evaluation of the average amplitude of the magnetic noise of magnetomodulation sensors with an amorphous ferromagnetic core operating in the mode of auto-parametric amplification has been carried out. It is shown that the average amplitude of the magnetic noise of magnetomodulation sensors can be ~0.45 pT at a frequency of 0.1 Hz and less than 0.1 pT at frequencies above 3 Hz.
