Counterintuitive consequence of heating in strongly-driven intrinsic junctions of Bi2 Sr2 CaCu2 O 8+δ mesas
(American Physical Society, 2010-06)
Anomalously high and sharp peaks in the conductance of intrinsic Josephson junctions in Bi2 Sr2 CaCu2 O 8+δ (Bi2212) mesas have been commonly interpreted as superconducting energy gaps but here we show they are a result ...
Full bulk spin polarization and intrinsic tunnel barriers at the surface of layered manganites
(Nature Publishing Group, 2005-01)
The affect of full bulk spin polarization and intrinsic tunnel barriers on the surface of layered manganites were studied using a combination of surface-sensitive x-ray and tunnelling process. The surface bilayer of ...
Low-field behavior of Ti-added MgB2/Cu superconducting wires
We report on low-field magnetic properties of Ti-added (0-20 wt.% of Ti) Cu-clad MgB2 superconducting wires. Wires were produced by mixing appropriate amount of Ti and reacted MgB2 powder which was then placed inside Cu ...
Thermal management in large Bi2212 mesas used for terahertz sources
We present a thermal analysis of a patterned mesa on a Bi 2Sr2CaCu2O8 (Bi2212) single crystal that is based on tunneling characteristics of the c-axis stack of ∼800 intrinsic Josephson junctions in the mesa. Despite the ...
