Local antiferromagnetic correlations in the iron pnictide superconductors LaFeAsO{1-x}F{x} and Ca(Fe,Co)2As2 as seen via normal-state susceptibility
R. Klingeler, N. Leps, I. Hellmann +11
We have studied the interplay of magnetism and superconductivity in LaFeAsOF and Ca(FeCo)As. While antiferromagnetic spin density wave formation is…
Unusual field dependence of remanent magnetization in granular CrO2: possible role of piezomagnetism
A. Bajpai, R. Klingeler, N. Wizent +3
We present low field thermoremanent magnetization (TRM) measurements in granular CrO2 and composites of ferromagnetic (FM) CrO2 and antiferromagnetic (AFM) Cr2O3. TRM in these samp…
On the electronic structure of electron doped LaOFeAs as seen by X-ray absorption spectroscopy
T. Kroll, S. Bonhommeau, T. Kachel +14
We investigated the recently found superconductor LaO_{1-x}F_xFeAs by X-ray absorption spectroscopy (XAS). From a comparison of the O K-edge with LDA calculations we find good agre…
Crossover from one-dimensional copper-oxygen chains to two-dimensional ladders charge transport in (La,Y)y(Sr,Ca)14-yCu24O41
T. Ivek, T. Vuletic, B. Korin-Hamzic +8
The charge transport in the copper-oxygen chain/ladder layers of (La,Y)y(Sr,Ca)14-yCu24O41 is investigated along two crystallographic directions in the temperature range from 50 K…
Pseudogap-driven Hall effect sign reversal
D. V. Evtushinsky, S. V. Borisenko, A. A. Kordyuk +6
We present a calculation of the Hall coefficient in 2H-TaSe2 and 2H-Cu0.2NbS2 relied on the photoemission data and compare the results to transport observations. The approach, base…
Excitation energy map of the high-energy dispersion anomalies in cuprates
D. S. Inosov, R. Schuster, A. A. Kordyuk +8
The anomalous high-energy dispersion of the conductance band in the high-Tc superconductor Pb-Bi2212 has been extensively mapped by angle-resolved photoemission (ARPES) as a functi…
