Magnetic-field induced band-structure change in CeBiPt
N. Kozlova, J. Hagel, M. Doerr +11
We report on a field-induced change of the electronic band structure of CeBiPt as evidenced by electrical-transport measurements in pulsed magnetic fields. Above ~25 T, the charge-…
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…
Irreversible Magnetization Deep in the Vortex-Liquid State of a 2D Superconductor at High Magnetic Fields
T. Maniv, V. Zhuravlev, J. Wosnitza +1
The remarkable phenomenon of weak magnetization hysteresis loops, observed recently deep in the vortex-liquid state of a nearly two-dimensional (2D) superconductor at low temperatu…
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 …
Superconducting energy gap distribution of MgB investigated by point-contact spectroscopy
F. Laube, G. Goll, J. Hagel +3
We performed point-contact spectroscopy on the binary superconductor MgB. The differential conductance shows gap-related structures which vary in width and position from contac…
Field-induced metal-insulator transition in a two-dimensional organic superconductor
J. Wosnitza, S. Wanka, J. Hagel +9
The quasi-two-dimensional organic superconductor beta-(BEDT-TTF)_2SF_5CH_2CF_2SO_3 (T_c approx 4.4 K)shows very strong Shubnikov-de Haas (SdH) oscillations which are superimposed o…
