Observation of electronic bound states in charge-ordered YBaCuO
R. Zhou, M. Hirata, T. Wu +11
Observing how electronic states in solids react to a local symmetry breaking provides insight into their microscopic nature. A striking example is the formation of bound states whe…
Evidence of Andreev bound states as a hallmark of the FFLO phase in -(BEDT-TTF)Cu(NCS)
H. Mayaffre, S. Kramer, M. Horvatić +4
Superconductivity is a quantum phenomena arising, in its simplest form, from pairing of fermions with opposite spin into a state with zero net momentum. Whether superconductivity c…
Incipient charge order observed by NMR in the normal state of YBa2Cu3Oy
T. Wu, H. Mayaffre, S. Krämer +6
The pseudogap regime of high-temperature cuprates harbours diverse manifestations of electronic ordering whose exact nature and universality remain debated. Here, we show that the…
Emergence of charge order from the vortex state of a high temperature superconductor
T. Wu, H. Mayaffre, S. Kramer +8
Evidence is mounting that charge order competes with superconductivity in high Tc cuprates. Whether this has any relationship to the pairing mechanism is unknown since neither the…
Glassy Transition in the Vortex Lattice of Ba(Fe0.93Rh0.07)2As2 superconductor, probed by NMR and ac-susceptibility
L. Bossoni, P. Carretta, M. Horvatić +3
By using Nuclear Magnetic Resonance and ac-susceptibility, the characteristic correlation times for the vortex dynamics, in an iron-based superconductor, have been derived. Upon co…
Magnetic-field-induced charge-stripe order in the high temperature superconductor YBa2Cu3Oy
T. Wu, H. Mayaffre, S. Kramer +6
Electronic charges introduced in copper-oxide planes generate high-transition temperature superconductivity but, under special circumstances, they can also order into filaments cal…
Homogeneous vs. inhomogeneous coexistence of magnetic order and superconductivity probed by NMR in Co and K doped iron pnictides
M. -H. Julien, H. Mayaffre, M. Horvatic +6
In Ba(Fe0.95Co0.05)2As2 all of the 75As NMR intensity at the paramagnetic resonance position vanishes abruptly below Tonset(SDW)=56 K, indicating that magnetic (spin density wave)…
Similar glassy features in the NMR response of pure and disordered La1.88Sr0.12CuO4
V. F. Mitrovic, M. -H. Julien, C. de Vaulx +4
High Tc superconductivity in La2-xSrxCuO4 coexists with (striped and glassy) magnetic order. Here, we report NMR measurements of the 139La spin-lattice relaxation, which displays a…
Comment on "Localized behavior near the Zn impurity in YBa2Cu4O8 as measured by nuclear quadrupole resonance"
M. -H. Julien, Y. Tokunaga, T. Feher +2
Williams and Kramer [Phys. Rev. B {\bf 64}, 104506 (2001)] have recently argued against the existence of staggered magnetic moments residing on several lattice sites around Zn impu…
Impurity induced Local Magnetism and Density of States in the superconducting state of YBa2Cu3O7
S. Ouazi, J. Bobroff, H. Alloul +6
Oxygen NMR is used to probe the local influence of nonmagnetic Zn and magnetic Ni impurities in the superconducting state of optimally doped high Tc YBa2Cu3O7. Zn and Ni induce a s…
Glassy Spin Freezing and NMR Wipeout Effect in the High-T_c Superconductor La1.90Sr0.10CuO4: What is the Relationship With Stripes ?
M. -H. Julien, A. Campana, A. Rigamonti +9
We report on 139La and 63Ccu NMR/NQR measurements in the high-Tc superconductor La1.90Sr0.10CuO4 with Tc=26.5 K. Spin fluctuations probed by 139La spin-lattice relaxation (T1), con…

Titusz Feher, Andras Janossy, Gabor Oszlanyi +5
We have measured the spin susceptibility of the underdoped high temperature superconductor, YBa2Cu4O8 by Gd^{3+} electron spin resonance in single crystals and aligned powders at s…
Cu NMR evidence for enhanced antiferromagnetic correlations around Zn impurities in YBa2Cu3O6.7
M. -H. Julien, T. Feher, M. Horvatic +5
Doping the high-Tc superconductor YBa2Cu3O6.7 with 1.5 % of non-magnetic Zn impurities in CuO2 planes is shown to produce a considerable broadening of 63Cu NMR spectra, as well as…

M. -H. Julien, F. Borsa, P. Carretta +3
A 63Cu and 139La NMR/NQR study of superconducting (Tc=7 K) La1.94Sr0.06CuO4 single crystal is reported. Coexistence of spin-glass and superconducting phases is found below ~5 K fro…
