Bandwidth tuning triggers interplay of charge order and superconductivity in two-dimensional organic materials
S. Kaiser, M. Dressel, Y. Sun +4
We observe charge-order fluctuations in the quasi-two-dimensional organic superconductor -(BEDT-TTF)2 SF5 CH2 CF2 SO3 both by means of vibrational spectroscopy, l…
Spin-zero anomaly in the magnetic quantum oscillations of a two-dimensional metal
J. Wosnitza, V. M. Gvozdikov, J. Hagel +4
We report on an anomalous behavior of the spin-splitting zeros in the de Haas-van Alphen (dHvA) signal of a quasi-two-dimensional organic superconductor. The zeros as well as the a…
High field magnetic resonant properties of beta'-(ET)2SF5CF2SO3
I. B. Rutel, S. A. Zvyagin, J. S. Brooks +7
A systematic electron spin resonance (ESR) investigation of the low temperature regime for the (ET)2SF5CF2SO3 system was performed in the frequency range of ~200-700 GHz, using bac…
Coherent vs incoherent interlayer transport in layered metals
J. Wosnitza, J. Hagel, J. S. Qualls +8
The magnetic-field, temperature, and angular dependence of the interlayer magnetoresistance of two different quasi-two-dimensional (2D) organic superconductors is reported. For …
Thermal activation between Landau levels in the organic superconductor -(BEDT-TTF)SFCHCFSO
M. -S. Nam, A. Ardavan, J. A. Symington +6
We show that Shubnikov-de Haas oscillations in the interlayer resistivity of the organic superconductor -(BEDT-TTF)SF CHCFSO become very pronounc…
Unusual temperature dependence of the London penetration depth in all-organic β``-(ET)_2SF_5CH_2CF_2SO_3 single crystals
R. Prozorov, R. W. Giannetta, J. Schlueter +4
The temperature dependence of the in-plane, λ_{\parallel}, and interplane, λ_{\perp}, London penetration depth was measured in the metal-free all-organic superconductor β-ET (see t…
