Biaxially textured cobalt-doped BaFe2As2 films with high critical current density over 1 MA/cm2 on MgO-buffered metal-tape flexible substrates
Takayoshi Katase, Hidenori Hiramatsu, Vladimir Matias +5
High critical current densities (Jc) > 1 MA/cm2 were realized in cobalt-doped BaFe2As2 (BaFe2As2:Co) films on flexible metal substrates with biaxially-textured MgO base-layers fabr…
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…
Atomically-flat, chemically-stable, superconducting epitaxial thin film of iron-based superconductor, cobalt-doped BaFeAs
Takayoshi Katase, Hidenori Hiramatsu, Hiroshi Yanagi +3
Epitaxial growth of Fe-based superconductors such as Co-doped SrFeAs (SrFeAs:Co) was reported recently, but has still insufficient properties for device application…
Water-induced superconductivity in SrFe2As2
Hidenori Hiramatsu, Takayoshi Katase, Toshio Kamiya +2
It has been considered that FeAs-based high transition temperature (high-Tc) superconductors need electron or hole doping by aliovalent ion substitution or large off-stoichiometry…
Heteroepitaxial growth and optoelectronic properties of layered iron oxyarsenide, LaFeAsO
Hidenori Hiramatsu, Takayoshi Katase, Toshio Kamiya +2
Epitaxial thin films of LaFeAsO were fabricated on MgO (001) and mixed-perovskite (La, Sr)(Al, Ta)O3 (001) single-crystal substrates by pulsed laser deposition using a Nd:YAG secon…
Superconductivity in Epitaxial Thin Films of Co-Doped SrFe2As2 with Bilayered FeAs Structures and their Magnetic Anisotropy
Hidenori Hiramatsu, Takayoshi Katase, Toshio Kamiya +2
Superconducting epitaxial films of Fe-based layered arsenide, Co-doped SrFe2As2, were grown at 700oC on mixed perovskite (La, Sr)(Al, Ta)O3 (001) single-crystal substrates by pulse…
