Sažetak
We report AC transport and non-linear DC electrical transport in single crystals of the organic conductor k-(BEDT-TTF)2Cu[N(CN)2]Cl. Non-linear conductivity emerges below 22 K, which is the temperature of canted antiferromagnetic ordering. A broad dielectric relaxation mode of moderate strength (De ~ 3´103) appears at 32 K, and weakens with temperature. The mean relaxation time, much larger than that expected for single-particle excitations, is thermally activated in a manner similar to the DC conductivity and saturates below 22 K. The observed dielectric response data give evidence of a collective mode contribution to the dielectric properties, which might be attributed to charged domain walls in a ferromagnetic domain structure. Non-linear conductivity similar to those observed for commensurate spin and charge density waves are found.
