Spin excitations and exchange couplings in the cuprate antiferromagnet La2CuO4

The spin excitations in La2CuO4, a two-dimensional spin- 1/2 Heisenberg antiferromagnet and parent compound of high-Tc superconductors, have been measured throughout the Brillouin zone using high-resolution inelastic neutron scattering. The observed dispersion relations show evidence for substantial...
