Abstract: Both theoretical considerations and experimental data point to a more complicated nature of the valence hole states in doped cuprates than is predicted by the Zhang-Rice model. Actually, we deal with a competition of a conventional hybrid Cu 3d-O 2p b"1g ∝ dx2-y2 state and purely oxygen nonbonding state with eux, y ∝ px(,) y symmetry. The latter reveals a nonquenched Ising-like orbital moment that gives rise to a novel spinless purely oxygen scenario of the magnetic response in doped cuprates with the oxygen localized orbital magnetic moments of the order of tenths of Bohr magneton. We consider the mechanism of (63, 65)Cu-O 2p transferred orbital hyperfine interactions due to the mixing of the oxygen O 2p orbitals with Cu 3p semicore orbitals. Quantitative estimates point to a large magnitude of the respective contributions to both the local field and electric field gradient, and their correlated character. © 2004 MAIK "Nauka/Interperiodica".
