Charge Order Breaks Magnetic Symmetry in Molecular Quantum Spin Chains
M. Dressel, M. Dumm, T. Knoblauch +3
Charge order affects most of the electronic properties but is believed not to alter the spin arrangement since the magnetic susceptibility remains unchanged. We present electron-sp…
Comprehensive transport studies of anisotropy and ordering phenomena in quasi-one-dimensional (TMTTF)2X salts (X = PF6, AsF6, SbF6; BF4, ClO4, ReO4)
B. Köhler, E. Rose, M. Dumm +2
The temperature dependent dc resistivity of the quasi-one-dimensional organic salts (TMTTF)2X ( X = PF6, AsF6, SbF6; BF4, ClO4, ReO4) has been measured in all three crystal directi…
Bandwidth-controlled Mott transition in kappa-(BEDT-TTF)2Cu[N(CN)2]Br{x}Cl{1-x}: Optical studies of correlated carriers
Michael Dumm, Daniel Faltermeier, Natalia Drichko +3
In the two-dimensional organic charge-transfer salts kappa-(BEDT-TTF)2Cu[N(CN)2]Br{x}Cl{1-x} a systematic variation of the Br content from x = 0 to 0.9 allows us to tune the Mott t…
Quasiparticles at the verge of localization near the Mott metal-insulator transition in a two-dimensional material
J. Merino, M. Dumm, N. Drichko +2
The dynamics of charge carriers close to the Mott transition is explored theoretically and experimentally in the quasi two-dimensional organic charge-transfer salt -(BEDT-TTF)$_…
Charge Localization due to RKKY Interaction in the Spin Glass AuFe
B. Gorshunov, A. S. Prokhorov, S. Kaiser +11
Measurements of electrodynamic response of of spin glass AuFe films in comparison with pure gold films are performed at frequencies from 0.3 THz (10 cm-1) up to 1000 THz (33000 cm-…
Bandwidth-controlled Mott transition in I. Optical studies of localized charge excitations
Daniel Faltermeier, Jakob Barz, Michael Dumm +7
Infrared reflection measurements of the half-filled two-dimensional organic conductors -(BEDT-TTF)Cu[N(CN)]BrCl were performed as a function of temperatu…
