Sažetak
A variety of organics with reduced dimensionality and strong Coulomb interactions between charges and spins display novel forms of ordering phenomena. These broken-symmetry phases and their excitations have been in the focus of intense activity in recent years. In this presentation we overview results of complex conductivity (Hz – MHz) and electric-field dependent measurements in the bond charge density wave phase of alpha-(BEDT-TTF)2I3 and in the canted antiferromagnetic phase of kappa-(BEDT-TTF)2Cu[N(CN)2]Cl. Observed dynamics is discussed within theoretical models for charge excitations and compared with the well-known fingerprints of the charge and spin density wave response to ac and dc electric fields.
