Advantageous grain boundaries in iron pnictide superconductors
Takayoshi Katase, Yoshihiro Ishimaru, Akira Tsukamoto +4
High critical temperature superconductors have zero power consumption and could be used to produce ideal electric power lines. The principal obstacle in fabricating superconducting…
Transport and magnetic properties of Co-doped BaFe_{2}As_{2} epitaxial thin films
Shyam Mohan, Toshihiro Taen, Hidenori Yagyuda +5
We report resistivity, Hall coefficient, current-voltage characteristics, and magneto-optical imaging measurements of epitaxial Co-doped BaFe_{2}As_{2} thin films deposited on MgO(…
High Critical Current Density 4 MA/cm2 in Co-Doped BaFe2As2 Epitaxial Films Grown on (La, Sr)(Al, Ta)O3 Substrates without Buffer Layers
Takayoshi Katase, Hidenori Hiramatsu, Toshio Kamiya +1
High critical current densities Jc of 4 MA/cm2 at 4 K were obtained in Co-doped BaFe2As2 (BaFe2As2:Co) epitaxial films grown directly on (La, Sr)(Al, Ta)O3 substrates by pulsed las…
DC superconducting quantum interference devices fabricated using bicrystal grain boundary junctions in Co-doped BaFe2As2 epitaxial films
Takayoshi Katase, Yoshihiro Ishimaru, Akira Tsukamoto +4
DC superconducting quantum interference devices (dc-SQUIDs) were fabricated in Co-doped BaFe2As2 epitaxial films on (La, Sr)(Al, Ta)O3 bicrystal substrates with 30deg misorientatio…
Josephson junction in cobalt-doped BaFe2As2 epitaxial thin films on (La, Sr)(Al, Ta)O3 bicrystal substrates
Takayoshi Katase, Yoshihiro Ishimaru, Akira Tsukamoto +4
Josephson junctions were fabricated in epitaxial films of cobalt-doped BaFe2As2 on [001]-tilt (La,Sr)(Al,Ta)O3 bicrystal substrates. 10m-wide microbridges spanning a 30-degrees-til…
