75As NMR studies of superconducting LaFeAsO0.9F0.1.

• H-J Grafe, David P. Paar, +8 authors Bernd Büchner
• Physical review letters
• 2008

We have performed 75As nuclear magnetic resonance measurements on aligned powders of the new LaFeAsO0.9F0.1 superconductor. In the normal state, we find a strong temperature dependence of the spin… (More)

Inelastic neutron-scattering measurements of incommensurate magnetic excitations on superconducting LiFeAs single crystals.

• Nazera Qureshi, Paul Steffens, +8 authors Markus Braden
• Physical review letters
• 2012

Magnetic correlations in superconducting LiFeAs were studied by elastic and by inelastic neutron-scattering experiments. There is no indication for static magnetic ordering, but inelastic… (More)

Nanoscale electronic order in iron pnictides.

• Guillaume Lang, H-J Grafe, +5 authors Bernd Büchner
• Physical review letters
• 2010

The charge distribution in RFeAsO1-xFx (R=La,Sm) iron pnictides is probed using As nuclear quadrupole resonance. Whereas undoped and optimally doped or overdoped compounds feature a single charge… (More)

Anomalous superconducting state in LiFeAs implied by the 75As Knight shift measurement.

• S-H Baek, Luminita Harnagea, Sabine Wurmehl, Bernd Büchner, H-J Grafe
• Journal of physics. Condensed matter : an…
• 2013

(75)As NMR investigation of a single crystal of superconducting LiFeAs is presented. The Knight shift and the in situ ac susceptibility measurements as a function of temperature and external field… (More)

Nuclear-magnetic-resonance evidence for charge inhomogeneity in stripe ordered La(1.8-x)Eu0.2Sr(x)CuO4.

• H-J Grafe, N J Curro, Markus Hücker, Bernd Büchner
• Physical review letters
• 2006

We report 17O nuclear-magnetic-resonance (NMR) results in the stripe ordered La(1.8-x)Eu0.2Sr(x)CuO4 system. Below a temperature T(q) approximately 80 K, the local electric field gradient and the… (More)

Spin gap in the zigzag spin-1/2 chain cuprate Sr(0.9)Ca(0.1)CuO(2).

• Franziska Hammerath, Satoshi Nishimoto, +6 authors Bernd Büchner
• Physical review letters
• 2011

We report a comparative study of (63)Cu nuclear magnetic resonance spin lattice relaxation rates T(1)(-1) on undoped SrCuO(2) and Ca-doped Sr(0.9)Ca(0.1)CuO(2) spin chain compounds. A temperature… (More)

NMR Evidence for Inhomogeneous Nematic Fluctuations in BaFe_{2}(As_{1-x}P_{x})_{2}.

• Adam P. Dioguardi, T. Kissikov, +7 authors N J Curro
• Physical review letters
• 2016

We present evidence for nuclear spin-lattice relaxation driven by glassy nematic fluctuations in isovalent P-doped BaFe_{2}As_{2} single crystals. Both the ^{75}As and ^{31}P sites exhibit a… (More)
