New Series of Nickel-Based Pnictide Oxide Superconductors (Ni2Pn2)(Sr4Sc2O6) (Pn = P, As)
Yutaka Matsumura, Hiraku Ogino, Shigeru Horii +3
We have discovered new nickel-based pnictide oxide superconductors, (Ni2Pn2)(Sr4Sc2O6) (Pn = P, As). These compounds have a tetragonal unit cell with a space group of P4/nmm and th…
New iron-based arsenide oxides (Fe2As2)(Sr4M2O6)(M = Sc, Cr)
Hiraku Ogino, Yukari Katsura, Shigeru Horii +2
We have discovered new layered oxyarsenides (Fe2As2)(Sr4M2O6) (M = Sc, Cr: M-22426). These materials are isostructural with (Fe2P2)(Sr4Sc2O6), which was found in our previous study…
Superconductivity at 17 K in (Fe2P2)(Sr4Sc2O6): a new superconducting layered pnictide oxide with a thick perovskite oxide layer
H. Ogino, Y. Matsumura, Y. Katsura +4
A new layered oxypnictide (Fe2P2)(Sr4Sc2O6) have been synthesized by solid-state reaction. This material has an alternating layer stacking structure of anti-fluorite Fe2P2 and pero…
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…
