摘要：
We summarize the main features of the low frequency dielectric relaxation observed below 30K: in the weak ferromagnetic start of kappa-(BEDT-TTF)(2)Cu[N(CN)(2)]Cl. The observed width of the: relaxation process is somewhat broader than for a Debye process and has a moderate strength of about 3.10(3). The mean relaxation time, which is much larger than expected for single particle excitations, is thermally activated in a manner similar to the de conductivity and saturates below the antiferromagnetic phase transition. A charged domain wall in a random ferromagnetic domain structure is proposed as the relaxation entity.
