Description
Summary:The temperature features of electrical conductivity in multicomponent organic spin glasses that possess hydrocarbon origin and consist of a dispersion diamagnetic hydrocarbon medium and nanodispersed paramagnetic asphaltene phase were studied. A phase transition from a dielectric state to a semiconductor one was observable in such systems at 65–85°C. The thermodynamic parameters of the temperature dependence of their electrical conductivity were determined.
