Abstract

The oxygen doping of delafossite compounds MCuO_2+δ allows the production of various networks of spins 1/2 (Cu²⁺) by the insertion of additional O atoms in the Cu layers that increase the valence of the Cu atoms. For instance, Δ-chains of spins 1/2 can be stabilized in YCuO_2.5. In this compound, some glassiness is revealed in magnetostatic measurements while a strongly correlated quasielastic magnetic signal, observed at high temperatures in neutron scattering experiments, decreases in intensity with decreasing T, reflecting a freezing process.
