Synthesis of -axis textured CaKFeAs superconducting bulk via spark plasma texturing technique
Shigeyuki Ishida, Yoshihisa Kamiya, Yoshinori Tsuchiya +7
Grain alignment is a key factor that determines the performance of a superconducting bulk. In this study, the spark plasma texturing (SPT) technique was used to fabricate a CaKFe$_…
Synthesis of CaKFeAs bulk samples with high critical current density using a spark plasma sintering technique
Shigeyuki Ishida, S. Pavan Kumar Naik, Yoshinori Tsuchiya +7
A high density CaKFeAs bulk sample was successfully synthesized using a spark plasma sintering (SPS) technique. The density of the synthesized sample was 5.02 g cm,…
Layer buckling and absence of superconductivity in LaNiO2
S. Rathnayaka, S. Yano, K. Kawashima +4
The recent observation of unconventional superconductivity in thin films of LaNiO2 (critical temperature, Tc~10 K) and in bulk single crystals of La3Ni2O7 (327) under pressure (Tc~…
Na-catalyzed rapid synthesis and characterization of intercalated graphite CaC6
Akira Iyo, Hiroshi Fujihisa, Yoshito Gotoh +4
In this study, we conducted experiments on CaC6 for elucidating the Na-catalyzed formation mechanism and achieving rapid mass synthesis of graphite intercalation compounds (GICs).…
Hidden Structural and Superconducting Phase Induced in Antiperovskite Arsenide SrPdAs
Akira Iyo, Hiroshi Fujihisa, Yoshito Gotoh +5
Enriching the material variation often contributes to the progress of materials science. We have discovered for the first time antiperovskite arsenide SrPdAs and revealed a h…
Posttreatment Effects on the Crystal Structure and Superconductivity of Ca-Free Double-Layered Cuprate SrSrCuOF
Hiroki Ninomiya, Kenji Kawashima, Hiroshi Fujihisa +6
We report the effects of low-temperature postannealing on the structural and superconducting properties of the recently discovered Ca-free double-layered cuprate, SrSrCuO$_…
