SPIN CORRELATIONS IN HIGH Tc SUPERCONDUCTORS

Abstract
A review is given of current neutron scattering experiments on La2-xSrxCuO4 and YBa2Cu3O6+x. Large single crystals have now been successfully grown for both of these high Tc superconductors and extensive measurements are being carried out on magnetic excitations for wide ranges of temperature and composition. A novel type of two-dimensional spin correlation is found with unusually large J2D ≈ 1 000 K.
