Antiferromagnetic Domain Structure in Bilayer Manganite
M. García-Fernández, S. B. Wilkins, Ming Lu +5
We report a novel soft x-ray nanodiffraction study of antiferromagnetic domains in the strongly correlated bylayer manganite LaSrMnO. We find that the…
Tunable terahertz emission from Bi2Sr2CaCu2O8+δ mesa devices
T. M. Benseman, A. E. Koshelev, K. E. Gray +5
We have measured coherent terahertz emission spectra from Bi2Sr2CaCu2O8+δ mesa devices, as a function of temperature and mesa bias voltage. The emission frequency is found to be tu…
Rebuttal to "Comment by V.M. Krasnov on 'Counterintuitive consequence of heating in strongly-driven intrinsic junctions of Bi2Sr2CaCu2O8+d Mesas' "
C. Kurter, L. Ozyuzer, T. Proslier +3
In our article [1], we found that with increasing dissipation there is a clear, systematic shift and sharpening of the conductance peak along with the disappearance of the higher-b…
Counterintuitive Consequence of Heating in Strongly-Driven Intrinsic-Junctions of BiSrCaCuO Mesas
C. Kurter, L. Ozyuzer, T. Proslier +3
Anomalously high and sharp peaks in the conductance of intrinsic Josephson junctions in BiSrCaCuO (Bi2212) mesas have been universally interpreted as supe…
Thermal Management in Large Bi2212 Mesas used for Terahertz Sources
C. Kurter, K. E. Gray, J. F. Zasadzinski +8
We present a thermal analysis of a patterned mesa on a Bi2Sr2CaCu2O8 (Bi2212) single crystal that is based on tunneling characteristics of the c-axis stack of ~800 intrinsic Joseph…
Emission of Terahertz Waves from Stacks of Intrinsic Josephson Junctions
K. E. Gray, L. Ozyuzer, A. E. Koshelev +8
By patterning mesoscopic crystals of Bi2Sr2CaCu2O8 (BSCCO) into electromagnetic resonators the oscillations of a large number of intrinsic Josephson junctions can be synchronized i…
