Paramagnetic Meissner Effect in Superconducting Single Crystals of Ba_{1-x}K_xBiO_3
Hyun-Tak Kim, H. Minami, W. Schmidbauer +4
The paramagnetic Meissner effect (PME) in the field cooled susceptibility has been observed in superconducting single crystals of Ba_{1-x}K_xBiO_3 using magnetometers of Quantum-De…
Direct imaging of hot spots in Bi_{2}Sr_{2}CaCu_{2}O_{8+δ} mesa terahertz sources
T. M. Benseman, A. E. Koshelev, W. -K. Kwok +5
Stacks of intrinsic Josephson junctions (IJJs) made from high-temperature superconductors such as Bi_{2}Sr_{2}CaCu_{2}O_{8+δ} (Bi-2212) are a promising source of coherent continuo…
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…
Cavity mode identification for coherent terahertz emission from a nearly square stack of intrinsic Josephson junctions
M. Tsujimoto, I. Kakeya, T. Kashiwagi +2
Stacks of intrinsic Josephson junctions in BiSrCaCuO emit intense and coherent terahertz waves determined by the internal electromagnetic cavity resonance. We…
Powerful terahertz emission from Bi2Sr2CaCu2O8+delta mesa arrays
T. M. Benseman, K. E. Gray, A. E. Koshelev +5
Stacks of intrinsic Josephson junctions (IJJs) in high-temperature superconductors enable the fabrication of compact sources of coherent terahertz radiation. Here we demonstrate th…
