Collisional stability of localized Yb() atoms immersed in a Fermi sea of Li
Hideki Konishi, Florian Schäfer, Shinya Ueda +1
We establish an experimental method for a detailed investigation of inelastic collisional properties between ytterbium (Yb) in the metastable state and ground st…
Oxypnictide SmFeAs(O,F) superconductor: a candidate for high-field magnet applications
Kazumasa Iida, Jens Haenisch, Chiara Tarantini +10
The recently discovered oxypnictide superconductor SmFeAs(O,F) is the most attractive material among the Fe-based superconductors due to its highest transition temperature of 56 K…
Fabrication of submicron LaSrCuO intrinsic Josephson junction stacks
Yuimaru Kubo, Yamaguchi Takahide, Takayoshi Tanaka +6
Intrinsic Josephson junction (IJJ) stacks of cuprate superconductors have potential to be implemented as intrinsic phase qubits working at relatively high temperatures. We report s…
Switching current distributions and subgap structures of underdoped (Hg,Re)Ba2Ca2Cu3O8+d intrinsic Josephson junctions
S. Ueda, T. Yamaguchi, Y. Kubo +4
We have investigated the intrinsic Josephson properties in slightly underdoped (Hg,Re)Ba2Ca2Cu3Oy [Hg(Re)1223] intrinsic Josephson junctions (IJJs) with a dimension of 1.0x1.5x0.11…
Resistivity reduction of boron-doped multi-walled carbon nanotubes synthesized from a methanol solution containing a boric acid
Satoshi Ishii, Tohru Watanabe, Shinya Ueda +3
Boron-doped multi-walled carbon nanotubes (MWNTs) were synthesized using a methanol solution of boric acid as a source material. Accurate measurements of the electrical resistivity…
Universal relationship between crystallinity and irreversibility field of MgB2
A. Yamamoto, J. Shimoyama, S. Ueda +4
The relationship between irreversibility field, Hirr, and crystallinity of MgB2 bulks including carbon substituted samples was studied. The Hirr was found to increase with an incre…
