Antiferromagnetic correlations near the lower edge of superconducting dome in YBCO6+x

Z. Yamani, W. J. L. Buyers, F. Wang +4

Neutron scattering from high-quality YBCO6.334 single crystals with a T${}_c$ of 8.4 K shows that there is no coexistence with long-range antiferromagnetic order at this very low, ne…
