Abstract:

One of the most exciting features of the hole centers CuO45- in doped cuprates is an unusually complicated ground state which is the result of the electronic quasi-degeneracy. An additional hole, doped to the basic CuO46- cluster with the b(1g) hole can occupy both the same hybrid Cu3d-O2p orbital state resulting in a Zhang-Rice singlet (1)A(1g) and the purely oxygen e(u) molecular orbital resulting in a singlet or triplet E-1.3(u) term with the close energies. We present detailed analysis of the (pseudo)-Jahn-Teller (PJT) effect driven by the near - degeneracy within the ((1)A(1g), E-1.3(u))-manifold. (C) 1999 Elsevier Science Ltd. All rights reserved.
