Abstract

High resolution inelastic neutron scattering was used to determine the magnetic excitations of the square-lattice spin antiferromagnet and high-T_c parent compound La₂CuO₄. Strong hybridization pathing around the Cu₄O₄ account for the cyclic or ring exchange providing an explanation for the measured dispersion relation. It was concluded that the magnetic interactions in the cuprates can be described by a one-band Hubbard model and the cyclic exchange interactions or the related electronic currents are important for superconductivity in the doped cuprates.
