Autor: Benedikt Hartmann, Max Müller, Lisa Seyler, Tobias Bäuerle, Tobias Wilferth, Nikolai Avdievitch, Loreen Ruhm, Anke Henning, Alexei Lesiv, Pavel Ivashkin, Michael Uder, Armin M Nagel
Publikováno v: PLoS ONE, Vol 16, Iss 6, p e0252935 (2021)
Deuterium Magnetic Resonance Spectroscopy (DMRS) is a non-invasive technique that allows the detection of deuterated compounds in vivo. DMRS has a large potential to analyze uptake, perfusion, washout or metabolism, since deuterium is a stable isotop

Origin of the glass-like dynamics in molecular metals κ-(BEDT-TTF)2X: implications from fluctuation spectroscopy and ab initio calculations
Autor: Jens Müller, Benedikt Hartmann, Robert Rommel, Jens Brandenburg, Stephen M Winter, John A Schlueter
Publikováno v: New Journal of Physics, Vol 17, Iss 8, p 083057 (2015)
We have studied the low-frequency dynamics of the charge carriers in different organic charge-transfer salts κ -(BEDT-TTF) _2 X with polymeric anions X by using resistance noise spectroscopy. Our aim is to investigate the structural, glass-like tran

Fine-tuning the Mott metal–insulator transition and critical charge carrier dynamics in molecular conductors
Autor: Benedikt Hartmann, Jens Müller, Takahiko Sasaki
Publikováno v: Philosophical Magazine. 97:3477-3494
The unique possibilities of fine-tuning their physical properties in the vicinity of the Mott metal–insulator transition make the quasi-two-dimensional organic charge-transfer salts -(BEDT-TTF)X unprecedented model systems for studying the fundamen

Autor: Elena Gati, N.H. Hoang, Harald Schubert, Benedikt Hartmann, John A. Schlueter, Peter Lunkenheimer, Jens Müller, Alois Loidl, Michael Lang
Publikováno v: IEEE Transactions on Magnetics. 50:1-7
The recently proposed multiferroic state of the charge-transfer salt {\kappa}-(BEDT-TTF)$_2$Cu[N(CN)$_2$]Cl [P. Lunkenheimer et al., Nature Mater., vol. 11, pp. 755-758, Sept. 2012] has been studied by dc-conductivity, magnetic susceptibility and mea

Nonlinear electronic transport in the anomalous metallic state of quasi-2D organic superconductors κ-(BEDT-TTF)2 X
Autor: Benedikt Hartmann, Robert Rommel, John A. Schlueter, Jens Müller, Jens Brandenburg
Publikováno v: physica status solidi (b). 250:568-574
We present measurements of the first- and third-harmonic voltage response in ac electronic transport measurements, representing the linear (ohmic) and nonlinear resistivity, respectively, of the quasi-two-dimensional (2D) organic superconductors κ-(

Ferroelectric properties of charge-orderedα−(BEDT−TTF)2I3
Autor: Jens Müller, Alois Loidl, Dieter Schweitzer, Michael Lang, Peter Lunkenheimer, Benedikt Hartmann, Stephan Krohns
Publikováno v: Physical Review B. 91
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-(BEDT-TTF)2Cu[N(CN)2]Cl, the polar order in this material is ascribed

Critical Slowing Down of the Charge Carrier Dynamics at the Mott Metal-Insulator Transition
Autor: Benedikt Hartmann, Jana Polzin, David Zielke, Takahiko Sasaki, Jens Müller
Publikováno v: Physical Review Letters. 114
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 transition (MIT). At the finite-temperature critical end point, we obse

Mott metal-insulator transition induced by utilizing a glass-like structural ordering in low-dimensional molecular conductors
Autor: Jens Müller, Takahiko Sasaki, Benedikt Hartmann
We utilize a glasslike structural transition in order to induce a Mott metal-insulator transition in the quasi-two-dimensional organic charge-transfer salt $\ensuremath{\kappa}\ensuremath{-}{\text{(BEDT-TTF)}}_{2}\mathrm{Cu}[\mathrm{N}{\text{(CN)}}_{
