Room-Temperature Calcium Intercalation into Graphite Catalyzed by Sodium
Akira Iyo, Shigeyuki Ishida, Hiroshi Eisaki +2
Calcium (Ca) insertion into graphite (C) has been considered to require elevated temperatures, and its occurrence at room temperature (RT) has been regarded as highly unlikely. Her…
Translational symmetry breaking in the electronic nematic phase of BaFe2As2
K. Koshiishi, L. Liu, K. Okazaki +13
The microscopic origin of the nematicity, namely, four-fold rotational symmetry breaking in iron-based superconductors has been controversial since its discovery. In particular, it…
Rapid and Scalable Synthesis of Alkali Metal-Intercalated C Superconductors
Akira Iyo, Hiroshi Fujihisa, Yoshito Gotoh +4
Alkali metal-intercalated C, ( = K, Rb, Cs, and their combinations), holds significant potential for practical applications due to its high superconducting…
The uncollapsed LaFe2As2 phase: compensated, highly doped, electron-phonon coupled, iron-based superconductor
Ilaria Pallecchi, Akira Iyo, Hiraku Ogino +2
The recently discovered LaFe2As2 superconducting compound, member of the 122 family of iron pnictide superconductors, becomes superconducting below Tc=13K, yet its nominal doping a…
