Origin of the glass-like dynamics in molecular metals -(BEDT-TTF)X: implications from fluctuation spectroscopy and calculations
J. Müller, B. Hartmann, R. Rommel +3
We have studied the low-frequency dynamics of the charge carriers in different organic charge-transfer salts -(BEDT-TTF)X with polymeric anions X by using resistance noise s…
Critical Slowing Down of the Charge Carrier Dynamics at the Mott Metal-Insulator Transition
B. Hartmann, D. Zielke, J. Polzin +2
We report on the dramatic slowing down of the charge carrier dynamics in a quasi-two-dimensional organic conductor, which can be reversibly tuned through the Mott metal-insulator t…
Mott metal-insulator transition induced by utilizing a glass-like structural ordering in low-dimensional molecular conductors
B. Hartmann, J. Müller, T. Sasaki
We utilize a glass-like structural transition in order to induce a Mott metal-insulator transition in the quasi-two-dimensional organic charge-transfer salt -(BEDT-TTF)Cu[N(…
Ferroelectric properties of charge-ordered alpha-(BEDT-TTF)2I3
P. Lunkenheimer, B. Hartmann, M. Lang +4
A detailed investigation of the out-of-plane electrical properties of charge-ordered alpha-(BEDT-TTF)2I3 provides clear evidence for ferroelectricity. Similar to multiferroic alpha…
Multiferroicity in the Mott Insulating Charge-Transfer Salt κ-(BEDT-TTF)Cu[N(CN)]Cl
M. Lang, P. Lunkenheimer, J. Müller +6
The recently proposed multiferroic state of the charge-transfer salt κ-(BEDT-TTF)Cu[N(CN)]Cl [P. Lunkenheimer et al., Nature Mater., vol. 11, pp. 755-758, Sept. 2012] has b…
Multiferroicity in an organic charge-transfer salt: Electric-dipole-driven magnetism
P. Lunkenheimer, J. Müller, S. Krohns +8
Multiferroics, showing simultaneous ordering of electrical and magnetic degrees of freedom, are remarkable materials as seen from both the academic and technological points of view…
