Pulsed ESR investigation of spin transport properties in the organic conductor (perylenyl)2(AsF6)0.75(PF6)0.35 · 0.85CH2Cl2

Abstract

Spin transport properties in the organic conductor (perylenyl2)+ X- were studies in the temperature range of 4-300 K. Being constant in the "metallic" range (Dmid = 1.8(2)cm2s-1, the diffusion constant Dmid exhibits a temperature activated behaviour in the low temperature range, at variance with the prediction invoking the model of an intrinsic semiconductor. A low-temperature divergence of the homogenous ESR line width, indicative of one-dimensional fluctuations, was also observed.
