Аннотация
This report presents the results of studying an anomalous increase in the conductivity in the Cr/polymer/Cu structure near the antiferromagnet/paramagnet phase transition in chromium. As a polymer, poly(diphenylene phtalide) in which the charge instability effect was observed before is used. It is found that, when approaching the phase transition temperature, current fluctuations in the system increase and switch the conductivity of the structure to a high-conducting state with anomalously low resistance near the phase transition. The results are interpreted with the allowance for a change in the charge carrier injection near the phase transition temperature in chromium.
