Metal nanofilms for magnetic field sensors

The gold and molybdenum nanofilms were used as a material for sensitive layers of the Hall type magnetic field sensors intended to conducting a long-term magnetic diagnostics of the systems with high radiation loads. An in situ testing of sensors based on the metal nanofilms had been carried out in the fluxes of reactor neutrons. It was shown that the nanofilms electrophysical characteristics remain unchanged up to neutron fluence of ∼ 10²⁴ n/m² at temperature of ∼ 130 deg. C.
