Superconducting and Semiconducting Magnetic Charge Transfer Salts: (BEDT-TTF)4AFe(C2O4)3.cntdot.C6H5CN (A = H2O, K, NH4)

TL;DR: In this paper, it was shown that the hexagonal layer motif [AM{sup III}(C{sub 2} O{sub 4} ]{sub 3}]{sup n-} containing bridging oxalate groups, which has been shown to form a wide variety of compounds with electronically inactive counter-cations having unusual cooperative magnetic properties, can also stabilize lattices containing the organic {pi}-donor BEDT-TTF.
Journal ArticleDOI

Magnetotransport studies of the organic superconductor kappa -(BEDT-TTF)2Cu(NCS)2 under pressure: the relationship between carrier effective mass and critical temperature

TL;DR: In this article, a simplified model of the band structure of kappa -(BEDT-TTF)2Cu(NCS)2 has been used to derive the bare band masses of the electrons from optical data.
Journal ArticleDOI

Magnetic breakdown and quantum interference in the quasi-two-dimensional superconductor in high magnetic fields

TL;DR: In this paper, the authors investigated the magnetic breakdown phenomena in the longitudinal magnetoresistance of the quasi-two-dimensional (Q2D) superconductor kappa-(BEDT-TTF)(2)Cu(NCS) in magnetic fields of up to 50 T, well above the characteristic breakdown field.
Journal ArticleDOI

Dehaas-vanalphen Study of the Charge-transfer Salt Alpha-(bedt-ttf)(2)khg(scn)(4) in Pulsed Magnetic-fields of Up To 54 T

TL;DR: Analysis of the amplitude of the quantum oscillations within the framework of a two-dimensional Lifshitz-Kosevich model reveals that this material appears to be only fully transformed into the high-field state at fields above similar to 27 T, where the quasiparticle scattering rate is observed to be low.
Journal ArticleDOI

High-field magnetoresistance oscillations in α-[bis(ethylenedithio)tetrathiafulvalene]2KHg(SCN)4: The effects of magnetic breakdown, exchange interactions, and Fermi-surface reordering

TL;DR: In this paper, the authors examined the character of the Shubnikov-de Haas oscillations for a range of samples, temperatures, and field regimes to understand the role played by spin splitting and magnetic breakdown effects.
