Alternating current Josephson effect in intrinsic Josephson bridges in Tl2Ba2CaCu2O8 thin films
We have performed transport measurements on bridges patterned in misaligned thin films of the superconductor Tl2Ba2CaCu2O8. There is a c-axis component of current flow along the bridge, giving rise to hysteretic Josephson-like current-voltage curves. The temperature dependence of the critical curren...

| description | We have performed transport measurements on bridges patterned in misaligned thin films of the superconductor Tl2Ba2CaCu2O8. There is a c-axis component of current flow along the bridge, giving rise to hysteretic Josephson-like current-voltage curves. The temperature dependence of the critical current follows the Ambegaokar-Baratoff theory with IcRN up to 26 mV at 4.2 K. Microwave emission from the Josephson junctions near Tc (≈103 K) has been detected using an X-band detector. We show that 700±15 junctions in the bridge are actively oscillating, confirming that the junctions are "intrinsic" junctions formed by adjacent copper oxide planes in the Tl2Ba2CaCu2O8 crystal structure. © 2000 American Institute of Physics. |
