Abstract: The paper reveals the results of studies of the effect of electric current on the conductivity of the (Co$_{40}$Fe$_{40}$B$_{20}$)$_x$(SiO$_2$)$_{100-x}$ nanocomposite in the composition of a metal/nanocomposite/metal capacitor-type structure. It is shown that at a high measurement current, when the reduced power exceeds 0.1 W/mm$^2$, the film is heated. At a power greater than 2 W/mm$^2$, the temperature of the sample reaches values that lead to irreversible changes in the structure of the composite. A decrease in the density of localized states in the intergranular dielectric space during thermal exposure is the determining factor in reducing the conductivity of the nanocomposite.

Keywords: resistive switching, memristors, nanocomposite, electric properties.
