Polarized IR Reflectance Studies of the Organic Conductor k-(BETS)2FeCl4

چکیده
The infrared and Raman spectra of neutral bis(ethylenedithio)tetraselenafulvalene (BETS) as powder sample is reported. An assignment of the fundamental vibrational modes is presented and discussed; the vibrations are assigned using correlations between the obtained data and those for similar compounds: BEDT-TTF and BEDO-TTF. The results are used for analysis of absorption spectra and microreflectance polanzed IR spectra of single crystal ~-(BETS)2FeC14. The vibrational features of the spectra have been essentially assigned to a mixture of normally-inactive totally-symmetric Ag modes and IR-active modes of other symmetries. A general discussion of the origin of the electromc bands is given also. To our knowledge, the first spectral investigation of BETS and its sait are presented in this

IV-D Development of Magnetic Organic Superconductors
BETS-based salts incorporating Fe3+ ions are most interesting candidate systems for the observation of interplay of conductivity and magnetism. Indeed, in λand κ-(BETS)2FeCl4, conduction electrons in the BETS layers do interact with spins localised on the FeCl4 anions. Since the size of non-magnetic GaX4 anion (X = Cl, Br) approximatly equal to that of FeX4, (BETS)2GaX4 system can take the crys...
متن کاملAntiferromagnetic Insulating Ground State of Molecular -d System -(BETS)2FeCl4 (BETS = Bis(ethylenedithio)tetraselenafulvalene): A Theoretical and Experimental Review
The π-d molecular conductor λ-(BETS)2FeCl4, where BETS is bis(ethylenedithio) tetraselenafulvalene, has attracted considerable interest for the discovery of its field induced superconducting state. A mystery of this system is its antiferromagnetic insulating ground state. The point still under strong debate is whether the d spins in Fe3+ are ordered or not. Here, we review experimental and theo...
متن کاملMagnetic field-induced superconductivity: A unique interplay between magnetic and superconducting orderings. (March 3, 2004)
The complex interplay between magnetism and superconductivity is a central topic in condensed matter physics due to increasing evidence indicating that unconventional superconductivity (SC) occurs in the vicinity of magnetically ordered states. The experimental observations inspired models proposing "magnetically mediated" SC pairing in the proximity of magnetic quantum-criticality in a variety...
متن کاملNMR in the Organic Conductor κ-(BETS)2Mn[N(CN)2]3
Properties of the spin systems of the localized 3d Mn ions and the conduction π electrons in quasi-two-dimensional organic conductor κ-(BETS)2Mn[N(CN)2]3 were accessed using H and C NMR in order to find their relation to the metal-insulator transition which occurs at ∼23K. The transition of the system into the insulating state is shown to be followed by localization of the π spins into a long-r...
متن کاملQuasi index matching for minimum reflectance at a dielectric-conductor interface for obliquely incident p- and s-polarized light.
Conditions for reducing the reflectance of a dielectric-conductor interface for p- and s-polarized light to a minimum at any angle of incidence phi are determined. The refractive indices of a transparent immersion medium (liquid) that achieve minimum reflectance at normal incidence, phi=0, and at phi=45 degrees are independent of polarization. These indices provide sufficient data to determine ...
