Anomalous high-energy spin excitations in the high-Tc superconductor-parent antiferromagnet La₂CuO₄.
Inelastic neutron scattering is used to investigate the collective magnetic excitations of the high-temperature superconductor-parent antiferromagnet La2CuO4. We find that while the lower energy excitations are well described by spin-wave theory, including one- and two-magnon scattering processes, t...
