Abstract

The temperature dependences of conductivity σ(T), magnetoresistance (MR) and ESR signal of ion-irradiated polyimide films have been investigated. The transition from a variable to constant activation energy in the dependence σ(T) is observed to occur with decreasing temperature. This transition was accompanied by appearance of anomalous large negative MR and deviation of temperature behavior of ESR signal from Curie's law. It is suggested, that these phenomena are connected with magnetic ordering in the system of localized spins.
