  The prospects of using nanofilms of indium-containing III-V semiconductors,
gold and single-layer graphene in magnetic field sensors, intended for
application in radiation environment were evaluated on the results of testing
in neutron fluxes. Semiconductor sensors are capable of withstanding radiation
levels typical for the ITER-type fusion reactors, while gold sensors are stable
even under environment expected in the first fusion power plant DEMO. Graphene
is promising for creating sensors that combine high magnetic field sensitivity
and high irradiation resistance.
