Abstract

During studies of magnetoresistance of disordered systems composed of CSA-doped PPy or PANI in PMMA, striking periodic pulses in potential were detected which changed nature depending on temperature, magnetic field, applied current, and fabrication process. Extensive measurements show some more new features. The transition from regular pulsing to chaos is clearly seen, and may be controlled in a given sample by bias current, temperature and/or applied magnetic field.
