Superconducting flux qubit with ferromagnetic Josephson -junction operating at zero magnetic field
Sunmi Kim, Leonid V. Abdurakhimov, Duong Pham +6
Conventional superconducting flux qubits require the application of a precisely tuned magnetic field to set the operation point at half a flux quantum through the qubit loop, which…
Atomic Layer Deposition of Aluminum (111) Thin Film by Dimethylethylaminealane Precursor
Sameh Okasha, Yoshiaki Sekine, Satoshi Sasaki +1
We report the growth of aluminum (111) thin film by atomic layer deposition (ALD) technique with dimethylethylaminealane (DMEAA) as a precursor. It is found that the metallic under…
Angle-resolved photoemission spectroscopy of the low-energy electronic structure of superconducting PrCuO driven by oxygen non-stoichiometry
M. Horio, Y. Krockenberger, K. Koshiishi +8
Bulk crystals of electron-doped cuprates with the T'-type structure require both Ce substitutions and reduction annealing for the emergence of superconductivity while the reduction…
Electron Paramagnetic Resonance Spectroscopy of Er:YSiO Using Josephson Bifurcation Amplifier: Observation of Hyperfine and Quadrupole Structures
Rangga P. Budoyo, Kosuke Kakuyanagi, Hiraku Toida +4
We performed magnetic field and frequency tunable electron paramagnetic resonance spectroscopy of an Er doped YSiO crystal by observing the change in flux induced on…
Electronic Structure of Ce-Doped and -Undoped NdCuO Superconducting Thin Films Studied by Hard X-ray Photoemission and Soft X-ray Absorption Spectroscopy
M. Horio, Y. Krockenberger, K. Yamamoto +11
In order to realize superconductivity in cuprates with the T'-type structure, not only chemical substitution (Ce doping) but also post-growth reduction annealing is necessary. In t…
Photoresponse of LaSrCuO nanostrip
H. Shibata, N. Kirigane, K. Fukao +3
We report the fabrication and photoresponse of 5 nm thick LaSrCuO nanostrip with a width of 100nm. The I-V characteristics of the nanostrip show a hysteresi…
