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…
NQR Study of Spin-Freezing in Superconducting La2-xSrxCuO4: The Example of x=0.06
M. -H. Julien, P. Carretta, F. Borsa
NQR 139La and 63Cu spin-lattice relaxation rate (1/T_1) measurements in a La1.94Sr0.06CuO4 single crystal are described. Slowing-down of Cu2+ spin fluctuations is evidenced through…
Proton NMR for Measuring Quantum-Level Crossing in the Magnetic Molecular Ring Fe10
M. -H. Julien, Z. H. Jang, A. Lascialfari +4
The proton nuclear spin-lattice relaxation rate 1/T1 has been measured as a function of temperature and magnetic field (up to 15 T) in the molecular magnetic ring Fe10. Striking en…
Charge Segregation, Cluster Spin-Glass and Superconductivity in La1.94Sr0.06CuO4
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…
