Magnetism in BEDT-TTF materials
Strong commensurate antiferromagnetism proximate to superconductivity is found in some members of the κ-(ET) family, while a spin gap (SG) is found in the θ-(ET). Both κand θ-(ET) materials have frustrated triangular lattice structures. We show from calculations of spin-spin correlations within the effective half-filled band triangular lattice proposed for the κ-ET, as well as for the real latt...
متن کاملSpin-Fluctuation Mechanism of Superconductivity in Cuprates
Normal and superconducting state spectral properties of cuprates are theoretically described within the extended t-J model. The method is based on the equations of motion for projected fermionic operators and the mode-coupling approximation for the self-energy matrix. The dynamical spin susceptibility at various doping is considered as an input, extracted from experiments. The analysis shows th...
متن کاملSpin - fluctuation superconductivity in the Hubbard model
The theory of the superconductivity mediated by kinematic and exchange interactions in t?J and two-band Hubbard models in a paramagnetic state is formulated. The Dyson equations for the matrix Green functions in terms of the Hubbard operators are obtained in the non-crossing approximation. To calculate superconducting T c a numerical solution of self-consistent Eliashberg equations is proposed.
متن کاملElectron-Transfer Boat-Vibration Mechanism for Superconductivity in Organic Molecules Based on BEDT-TTF
The highest T, organic superconductors all involve the organic molecule bis(ethy1enedithio)tetrathiafulvalene (denoted as BEDT-TTF or ET) coupled with an appropriate acceptor. This leads to ET, ET+, or (ET)2+ species in the crystal. Using ab initio Hartree-Fock calculations (6-31G** basis set), we show that ET deforms to a boat structure with an energy 28 meV (0.65 kcallmol) lower than that of ...
متن کاملChemo- and enantioselective sulfoxidation of bis(ethylenedithio)-tetrathiafulvalene (BEDT-TTF) into chiral BEDT-TTF-sulfoxide.
Selective sulfoxidation of BEDT-TTF (bis(ethylenedithio)-tetrathiafulvalene) with enantiopure (camphoryl-sulfonyl)oxaziridine derivatives provided the inner monosulfoxide, as demonstrated using single crystal X-ray analysis, with an enantiomeric excess of 44% (up to 74% after recrystallization).
