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…
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…
Unconventional Multi-gap Superconductivity and Antiferromagnetic Spin Fluctuations in New Iron-arsenide LaFe2As2 in Heavily Electron-doped Regime
T. Kouchi, M. Yashima, H. Mukuda +5
We report 75As-NMR/NQR results on new iron-arsenide compounds (La0.5-xNa0.5+x)Fe2As2. The parent compound x=0 exhibits a stripe-type antiferromagnetic (AFM) order below T_N=130 K.…
Signature of multigap nodeless superconductivity in CaKFe4As4
P. K. Biswas, A. Iyo, Y. Yoshida +3
A newly discovered family of high-Tc Fe-based superconductors, AeAFe4As4 (Ae = Ca, Sr, Eu and A = K, Rb, Cs), offers further opportunities to understand unconventional superconduct…
