Spatial competition of the ground states in 1111 iron pnictides
G. Lang, L. Veyrat, U. Graefe +5
Using nuclear quadrupole resonance, the phase diagram of 1111 FeAsOF (La, Ce, Sm) iron pnictides is constructed as a function of the local charge distribution…
High-field electron spin resonance spectroscopy study of GdOFFeAs superconductors
A. Alfonsov, F. Murányi, V. Kataev +16
We report a detailed investigation of GdOFFeAs (x = 0, 0.07 and 0.14) samples by means of high-field/high-frequency electron spin resonance (HF-ESR) together with mea…
Nanoscale electronic order in iron pnictides
G. Lang, H. -J. Grafe, D. Paar +5
The charge distribution in RFeAsOF (R=La, Sm) iron pnictides is probed using As nuclear quadrupole resonance. Whereas undoped and optimally-doped or overdoped compounds…
Spin correlations and cobalt charge states: A new phase diagram of sodium cobaltates
G. Lang, J. Bobroff, H. Alloul +2
Using 23Na NMR measurements on sodium cobaltates at intermediate dopings (0.44<=x<=0.62), we establish the qualitative change of behavior of the local magnetic susceptibility at x*…
Interplay between magnetic properties and thermoelectricity in misfit and Na cobaltates
J. Bobroff, S. Hebert, G. Lang +3
We present a comparative study of CoO2 layers in the Bi-misfit and NaxCoO2 cobaltates. Co NMR measures the intrinsic susceptibility of the Co layers and is not affected by spurious…
Evidence of a single nonmagnetic Co3+ state in the Na1CoO2 cobaltate
G. Lang, J. Bobroff, H. Alloul +3
Macroscopic magnetization, muon spin rotation (muSR), and NMR measurements were carried out to study magnetism in the Na1CoO2 cobaltate. Using SQUID measurements, Na1CoO2 is shown…
