Abstract:

One of the most interesting attributes of a hole CuO45 center in doped cuprates is the complexity of the ground state as a result of electronic pseudodegeneracy. An extra hole injected into the initial CuO46 cluster with a b(1g) hole can occupy not only the very same hybrid Cu 3d-O 2p orbital state, producing a Zhang-Rice A(1g) singlet, but also the pure oxygen e(u) state, generating a singlet or triplet E-1,3(u) term, with close energies. The pseudo Jahn-Teller effect 1 induced by pseudodegeneracy of the singlet (1)A(1g) and E-1(u) terms is analyzed in detail. (C) 1998 American Institute of Physics. {[}S1063-7834(98)00610-8].
