Tuning Charge Order in -(BEDT-TTF)Hg(SCN)X (X=Br, Cl) via Uniaxial Strain
Jesse Liebman, Svetlana Torunova, John A. Schlueter +2
In condensed matter physics, experimental control over material properties reflects a deep understanding of the underlying physics. In recent years, meaningful progress has been ma…

Sudip Pal, Björn Miksch, Hans-Albrecht Krug von Nidda +10
The nature of the magnetic ground state of highly frustrated systems remained puzzling to this day. Here, we have performed multifrequency electron spin resonance (ESR) measurement…
Phase coexistence at the first-order Mott-transition revealed by pressure-dependent dielectric spectroscopy of -(BEDT-TTF)Cu(CN)
R. Rösslhuber, A. Pustogow, E. Uykur +7
The dimer Mott insulator -(BEDT-TTF)Cu(CN) can be tuned into a metallic and superconducting state upon applying pressure of 1.5 kbar and more. We have performed diel…
Probing magnetic order and disorder in the one-dimensional molecular spin chains CuF2(pyz) and [Ln(hfac)3(boaDTDA)]n (Ln=Sm, La) using implanted muons
T. Lancaster, B. M. Huddart, R. C. Williams +9
We present the results of muon-spin relaxation (SR) measurements on antiferromagnetic and ferromagnetic spin chains. In antiferromagnetic CuF(pyz) we identify a transi…
Quantum Spin Liquids Unveil the Genuine Mott State
A. Pustogow, M. Bories, A. Löhle +14
The Widom line identifies the locus in the phase diagram where a supercritical gas crosses over from gas-like to a more liquid-like behavior. A similar transition exists in correla…
Weak ferromagnetism and glassy state in kappa-(BEDT-TTF)2Hg(SCN)2Br
M. Hemmida, H. -A. Krug von Nidda, B. Miksch +8
Since the first observation of weak ferromagnetism in the charge-transfer salt kappa-(BEDT-TTF)2-Cu[N(CN)2]Cl [U. Welp et al., Phys. Rev. Lett. 69, 840 (1992)], no further evidence…

G. Koutroulakis, H. Kühne, H. H. Wang +3
A C NMR study of the normal and superconducting states of the all-organic charge-transfer salt -(BEDT-TTF)SFCHCFSO is presented. We find that the nor…
