Persistence to High Temperatures of Interlayer Coherence in an Organic Superconductor

Sum rules and interlayer infrared response of the high temperature YBa2Cu3Oy superconductor in an external magnetic field.

We present infrared magneto-optical measurements of the c-axis conductivity of YBa2Cu3Oy in both the underdoped (y=6.67 and 6.75) and optimally doped (y=6.95) regimes. We show that modest c-axis magnetic fields radically modify the condensate formation and restore conventional BCS-like energetics. Additionally, we demonstrate the pivotal role of interplane coherence in the anomalous high-energy...

Interlayer magnetoresistance in the organic superconductor k-„BEDT-TTF...2Cu†N„CN...2‡Br near the superconducting transition

In this paper, we report transport measurements of interlayer magnetoresistance with field parallel and perpendicular to the current direction in the organic superconductor k-(BEDT-TTF)2Cu@N(CN)2#Br. For HiJ , the isothermal magnetoresistance R(H) displays a peak effect as a function of field. While the magnetoresistance at small field can be fitted to stacked Josephson junction model, the nega...
