Cu hyperfine coupling constants of HgBa $_{2}$ CaCu $_{2}$ O $_{6 + δ}$

Y. Itoh, T. Machi, A. Yamamoto

We estimated the ratios of $^{63}$ Cu hyperfine coupling constants in the double-layer high- $T_{c}$ superconductor HgBa $_{2}$ CaCu $_{2}$ O $_{6 + δ}$ from the anisotropies in Cu nucle…

Magnetic susceptibility of optimally doped HgBa $_{2}$ CuO $_{4 + δ}$

Y. Itoh, T. Machi, A. Yamamoto

The magnitude of the powder spin susceptibility of an optimally doped superconductor HgBa $_{2}$ CuO $_{4 + δ}$ (Hg1201) in the normal state is found to be nearly the same as that of La$_…

Strong coupling superconductivity at 8.4 K in an antiperovskite phosphide SrPt3P

T. Takayama, K. Kuwano, D. Hirai +3

We report the discovery of a family of ternary platinum phosphides APt3P (A = Ca, Sr and La), which crystallize in an antiperovskite-based structure closely related to that of the…

Effects of carbon incorporation on doping state of YBa2Cu3Oy

A. Yamamoto, K. Hirose, Y. Itoh +2

Effects of carbon incorporation on the doping state of YBa2Cu3Oy (Y-123) were investigated. Quantitative carbon analysis revealed that carbon could be introduced into Y-123 from bo…

Carbon-substituted MgB2 single crystals

Sergey Lee, Takahiko Masui, Ayako Yamamoto +2

Carbon-substituted MgB2 single crystals, Mg(B_1-xC_x)_2 of 0.3-1.0 mm size were grown for x=0.02-0.15 by a high-pressure technique. The doping dependence of lattice constants studi…
