Description
Sharp quasi-elastic peaks (κ=0.014 A-1, Γ=0.22 meV), indicating long-range antiferromagnetic slow fluctuations, were observed at (π,π)+ε(π,0) in La1.86Sr0.14Cu0.988Zn 0.012O4-δ in superconducting (δ=0, Tc=19 K) and non-superconducting (δ=0.0040) conditions. The quasi-elastic components start appearing around Tc and increase with lowering temperature, while the low-energy inelastic peaks with the same ε show a broad intensity maximum around the same temperature.
