Different superconducting percolation regimes in the layered organic Mott system $κ$ -(BEDT-TTF) $_{2}$ Cu[N(CN) $_{2}$ ]Cl -- evidence from fluctuation spectroscopy

Jens Mueller, Jens Brandenburg, John A. Schlueter

Fluctuation spectroscopy is used to investigate the organic bandwidth-controlled Mott system $κ$ -(BEDT-TTF) $_{2}$ Cu[N(CN) $_{2}$ ]Cl. We find evidence for percolative-type superconductiv…

Exchange parameters of copper-based quasi-two-dimensional Heisenberg magnets measured using high magnetic fields and muon-spin rotation

P. A. Goddard, J. Singleton, P. Sengupta +9

Pulsed-field magnetization experiments (fields $B$ of up to 85 T and temperatures $T$ down to 0.4 K) are reported on nine organic Cu-based two-dimensional (2D) Heisenberg magnets.…

Magnetic order in the S=1/2 two-dimensional molecular antiferromagnet, copper pyrazine perchlorate Cu(Pz)_2(ClO_4)_2

T. Lancaster, S. J. Blundell, M. L. Brooks +14

We present an investigation of magnetic ordering in the two-dimensional S=1/2 quantum magnet Cu(Pz)_2(ClO_4)_2 using specific heat and zero field muon-spin relaxation (μ^+SR). The…

Cyclotron resonance harmonics in the organic superconductor $β^{''}$ -(BEDT-TTF) $_{2}$ SF $_{5}$ CH $_{2}$ CF $_{2}$ SO $_{3}$ ; observation of a new kind of effective mass renormalization

R. S. Edwards, J. A. Symington, A. Ardavan +5

Cyclotron resonance, along with its second and third harmonics, has been observed in the quasi-two-dimensional organic superconductor $β^{''}$ -(BEDT-TTF) $_{2}$ SF $_{5}$ CH $_{2}$ C…

Electronic Structure of Novel Cation-Radical Salts in High Magnetic Fields

J. S. Brooks, L. Balicas, K. Storr +10

Two organic conducting materials, where unusual aspects of their composition play important roles, are explored: beta''-(BEDT-TTF)2SF5XSO3 which exhibits superconductivity, or a me…
