P. Barta et al., LOW-TEMPERATURE TRANSPORT-PROPERTIES OF POLY(3-ALKYLTHIOPHENE)S DOPEDWITH FECL4-, Journal of physics. Condensed matter, 7(14), 1995, pp. 187-191
This letter reports the results of temperature-dependent conductivity
measurements performed for a conjugated polymer doped with magnetic co
mplex. There, an abrupt decrease in conductivity was observed as tempe
rature was lowered. The phenomenon is interpreted as the effect of the
short-range magnetic order appearing and, consequently, affecting the
transport processes by magnetic interactions mediated by charge-carry
ing species (polarons, bipolarons). In addition, results of x-ray diff
raction experiments that were performed are discussed.
