A New Noncentrosymmetric Superconducting Phase in the Li-Rh-B System
Hiroyuki Takeya, Hiroki Fujii, Mohammed ElMassalami +6
Superconductivity, at 2-3 K, was observed in a novel phase of the ternary Li-Rh-B system. The structural phase exhibits a large noncentrosymmetric cubic unit cell with the a-parame…
Study of superconducting properties of MgB2
Y. Machida, S. Sasaki, H. Fujii +3
We synthesized single crystalline and policrystalline MgB_2 under ambient pressures. The single crystals of MgB_2 were of good quality, where the crystal structure refinements were…
A New Approach for the Fabrication of MgB2 Superconducting Tape with Large In-field Transport Critical Current Density
K. Komori, K. Kawagishi, Y. Takano +5
The paper reports the first successful fabrication of MgB2 superconducting tape using a flexible metallic substrate as well as its strong pinning force, which was verified by direc…
High transport critical current density obtained for Powder-In-Tube-processed MgB2 tapes and wires using stainless steel and Cu-Ni tubes
H. Kumakura, A. Matsumoto, H. Fujii +1
MgB2 tapes and wires were fabricated by the Powder-In-Tube method. Stainless steel and Cu-Ni tubes were used as sheath materials, and no heat treatment was applied. The tapes made…
Superconducting Properties of MgB2 Bulk Materials Prepared by High Pressure Sintering
Y. Takano, H. Takeya, H. Fujii +5
High-density bulk materials of a newly discovered 40K intermetallic MgB2 superconductor were prepared by high pressure sintering. Superconducting transition with the onset temperat…
