F. Sersen et al., ANTIFERROMAGNETISM OF POLY(3-DODECYLTHIOPHENE) IRRADIATED BY GAMMA-BEAMS, Journal of radioanalytical and nuclear chemistry, 212(1), 1996, pp. 1-9
The magnetic properties of poly(3-dodecyl-thiophene) (PDDT) irradiated
by gamma-beams have been studied by measuring the magnetic susceptibi
lity and EPR spectra. The irradiated PDDT is characterized, similarly
as the non-irradiated one, by an antiferromagnetic course of magnetic
susceptibility with a Neel temperature of 237 K. It is suggested that
the antiferromagnetic properties of PDDT are caused by transformation
of polarons to bipolarons, which takes place at lower temperatures.
