Mott localization in the correlated superconductor Cs3C60 resulting from the molecular Jahn-Teller effect
Katalin Kamaras, Gyongyi Klupp, Peter Matus +6
Cs3C60 is a correlated superconductor under pressure, but an insulator under ambient conditions. The mechanism causing this insulating behavior is the combination of Mott localizat…
Raman response of Stage-1 graphite intercalation compounds revisited
J. C. Chacón-Torres, A. Y. Ganin, M. J. Rosseinsky +1
We present a detailed in-situ Raman analysis of stage-1 KC8, CaC6, and LiC6 graphite intercalation compounds (GIC) to unravel their intrinsic finger print. Four main components wer…
Anomalous dependence of the c-axis polarized Fe B phonon mode with Fe and Se concentrations in FeTeSe
Y. J. Um, A. Subedi, P. Toulemonde +10
We report an investigation of the lattice dynamical properties in a range of FeTeSe compounds, with special emphasis on the c-axis polarized vibration of Fe w…
Cation vacancy order in the K0.8+xFe1.6-ySe2 system: five-fold cell expansion accommodates 20% tetrahedral vacancies
J. Bacsa, A. Y. Ganin, Y. Takabayashi +4
Ordering of the tetrahedral site vacancies in two crystals of refined compositions K0.93(1)Fe1.52(1)Se2 and K0.862(3)Fe1.563(4)Se2 produces a fivefold expansion of the parent ThCr2…
Anisotropic fluctuations and quasiparticle excitations in FeSe_0.5Te_0.5
A. Serafin, A. I. Coldea, A. Y. Ganin +4
We present data for the temperature dependence of the magnetic penetration depth lambda(T), heat capacity C(T), resistivity R(T) and magnetic torque ?tau for highly homogeneous sin…
Two-electronic component behavior in the multiband FeSeTe superconductor
D. Arcon, P. Jeglic, A. Zorko +5
We report X-band EPR and Te and Se NMR measurements on single-crystalline superconducting FeSeTe ( = 11.5(1) K). The data provide evidence for…
