A Novel BEDT-TTF-based Purely Organic Magnetic Conductor, α-(BEDT-TTF)2(TEMPO-N(CH3)COCH2SO3)·3H2O
A new BEDT-TTF-based salt with an organic free radical TEMPO has been prepared. The salt consists of alternate layers of conducting and magnetic sheets, between which are short S(BEDT-TTF)...O(TEMPO) contacts. The magnetic susceptibility is well modelled by the combination of a Curie-Weiss and a 2-D Heisenberg models with J = -89 K and θ = +0.05 K.
متن کاملMott-Anderson Transition in Molecular Conductors: Influence of Randomness on Strongly Correlated Electrons in the κ-(BEDT-TTF)2X System
The Mott-Anderson transition has been known as a metal-insulator (MI) transition due to both strong electron-electron interaction and randomness of the electrons. For example, the MI transition in doped semiconductors and transition metal oxides has been investigated up to now as a typical example of the Mott-Anderson transition for changing electron correlations by carrier number control in co...
متن کاملExtremely Slow Charge Fluctuations in the Metallic State of the Two-Dimensional Molecular Conductor - BEDT-TTF
216405-1 Large charge disproportionation has been confirmed in the metallic state of a 1=4-filled organic conductor BEDT-TTF 2RbZn SCN 4 by means of 13C-NMR analysis on a selectively 13C-enriched single crystal sample. By comparing the homogeneous and inhomogeneous linewidths, the temperature dependence of the extremely slow dynamics of charge fluctuations has been determined first. The exotic ...
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...
متن کاملField and frequency dependent transport in the two-dimensional organic conductor -(BEDT-TTF)2I3
The title compound undergoes a metal-insulator phase transition of unknown origm at TMI = 135 K. We studied the electrodynamic response of a-(BEDT~TTF)213
