Phase transitions in a model of BEDT-TTF compound electron subsystem
نویسندگان
چکیده
Model of electronic subsystem (BEDT-TTF)2X family is studied theoretically within Green function equation motion approach. The configurational representation the model Hamiltonian which allows analytical calculation energy spectrum developed. Effective takes into account strong intra-site Coulomb, intersite exchange interaction electrons and correlated hopping both conducting plane in transversal direction. With rise intraatomic Coulomb repulsion a gap opens transition to antiferromagnetic state realized. At external pressure decreasing temperature from insulator metallic phase occurs. experimental diagrams for quasi-twodimensional organic conductors with electron correlations are discussed.

Trie Hall coefficient, Ru (T) for organic conductors is strongly temperature dependent even if they are metallic. The temperature dependence of Ru (T) is found tu exhibit uneto-one correspondence with trie structure of the Fermi surface, hence con be called "Standard" for each surface. Ii turned Dut that the simple temperature-independent Ru (T) is only realized in a material where trie Fermi s...

α-(BEDT-TTF)2KHg(SCN)4 is considered to be in the charge-density-wave (CDW) state below 8 K. We present new magnetoresistance data suggesting that the material undergoes a series of field-induced CDW (FICDW) transitions at pressures slightly exceeding the critical pressure P c at which the zero-field CDW state is destroyed. Further, we argue that a novel kind of FICDW transitions, entirely dete...

In the nonmetallic state of the organic superconductor k-~BEDT-TTF)2Cu@N(CN)2#Br synthesized with deuterated BEDT-TTF molecule, an angle-dependent electron spin resonance signal below 6–8 K was found. This is interpreted in terms of an antiferromagnetic resonance. The signal was found only when the sample was rapidly cooled, corresponding to the characteristics in that the present salt stays cl...
متن کاملMagnetism 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...

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).
