Antiferromagnetic ordering in a 90 K copper oxide superconductor

J. A. Hodges, Y. Sidis, P. Bourges +3

Using elastic neutron scattering, we evidence a commensurate antiferromagnetic Cu(2) order (AF) in the superconducting (SC) high-${\mathrm{T}}_{\mathrm{c}}$ cuprate $\rm YBa_2(Cu_{1-y}Co_y)_3O_{7+δ}…
