Spin correlations and colossal magnetoresistance in HgCrSe
Chaojing Lin, Changjiang Yi, Youguo Shi +4
This study aims to unravel the mechanism of colossal magnetoresistance (CMR) observed in n-type HgCrSe, in which low-density conduction electrons are exchange-coupled to a…
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(…
Local density of states in the superconductor -(BEDT-TTF)Cu[N(CN)]Br
Sandra Diehl, Torsten Methfessel, Jens Müller +4
Low temperature scanning tunneling spectroscopy reveals the local density of states of the organic superconductor -(BEDT-TTF)Cu[N(CN)]Br, that was cut in-situ in ultra-h…
Disorder-induced gap in the normal density of states of the organic superconductor -(BEDT-TTF)Cu[N(CN)]Br
Sandra Diehl, Torsten Methfessel, Jens Müller +4
The density of states of the organic superconductor -(BEDT-TTF)Cu[N(CN)]Br, measured by scanning tunneling spectroscopy on \textit{in-situ} cleaved surfaces, reveals a l…
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…
