Valence and Na content dependences of superconductivity in NaxCoO2.yH2O
H. Sakurai, N. Tsujii, O. Suzuki +5
Various samples of sodium cobalt oxyhydrate with relatively large amounts of Na ions were synthesized by a modified soft-chemical process in which a NaOH aqueous solution was…
Superconductivity of MI(MII0.5, Si0.5)2 (MI=Sr and Ba, MII=Al and Ga), ternary silicides with the AlB2-type structure
Motoharu Imai, Kenji Nishida, Takashi Kimura +4
Ternary silicides MI(MII0.5, Si0.5)2 (MI=Sr and Ba, MII=Al and Ga) were prepared by Ar arc melting. Powder X-ray diffraction indicates that they have the AlB2-type structure, in wh…
Superconducting anisotropy and evidence for intrinsic pinning in single crystalline MgB
Ken'ichi Takahashi, Toshiyuki Atsumi, Nariaki Yamamoto +3
We examine the superconducting anisotropy of a metallic high- superconductor MgB by measuring the magnetic torque of a single crystal. The ani…
Single crystal MgB2 with anisotropic superconducting properties
M. Xu, H. Kitazawa, Y. Takano +5
The discovery of superconductor in magnesium diboride MgB2 with high Tc (39 K) has raised some challenging issues; whether this new superconductor resembles a high temperature cupr…
