    In this paper we present a penetration depth study on the newly discovered superconductors Li2Pd3B and Li2Pt3B. Surprisingly, the low-temperature penetration depth λ(T) demonstrates distinct behavior in these two isostructural compounds. In Li2Pd3B, λ(T) follows an exponential decay and...

    The spin density wave and its temperature dependence in oxypnictide are studied in a three-band model. The spin susceptibilities with various interactions are calculated in the random phase approximation (PPA). It is found that the spin susceptibility peaks around the M point show a spin density...

    Despite decades of progress, an understanding of unconventional superconductivity still remains elusive. An important open question is about the material dependence of the superconducting properties. Using the quasiparticle self-consistent GW method, we re-examine the electronic structure of...

    Ce substituted TlBiSrCeCaYCuFeO ( x=0-0.20) samples were synthesized to determine the effects of the higher valence ion substitution on superconductivity and structure of the Fe-doped Tl1212 derivatives. The normal state behavior for x=0 showed semiconductor-like behavior which gradually turned...

    We report the improvement of superconducting properties on substitution of Cr in excess at the Fe site in FeCrxSe and FeCrxSe0.5Te0.5. In the case of FeCrxSe, there is an increase in superconducting transition temperature (Tc) by ∼40% with a concomitant increase in the superconducting...

    The effect of a substitution site on orientation birefringence for cellulose triacetate (CTA) was investigated by the addition of xylan ester. Since CTA has three substitution sites (C-2, C-3, and C-6) while xylan ester has two substitution sites (C-2 and C-3), the change of birefringence by...
