© Springer Nature Singapore Pte Ltd. 2020.It was investigated the thermal stability of two types of Hall sensors based on gold nanofilms deposited on sapphire: (i) with the titanium adhesive sublayer (Ti/Au) and (ii) with the titanium adhesive sublayer and the platinum barrier sublayer of (Ti/Pt/Au). Vacuum annealing for 3 h at 400 °C significantly changes all investigated electrophysical parameters of samples with the Ti/Au metallization, which is explained by the titanium diffusion into gold. At the same time, the sensitivity and the resistivity of sensors with the Ti/Pt/Au metallization remain unchanged within a few percent, allowing them to be used in the plasma’s magnetic diagnostic systems of the ITER and DEMO fusion reactors where operating temperatures will exceed 300 °C.
