Doping-driven structural phase transition and loss of superconductivity in MxFe1-xSe delta (M=Mn, Cu)

Huang, TW; Chen, TK; Yeh, KW; Ke, CT; Chen, CL; Huang, YL; Hsu, FC; ... (11 authors) (2010)

In this paper, we report the results of detailed studies on Mn and Cu substitution to Fe site of beta-FeSe, namely, MnxFe(1-x)Se(1-delta) and CuxFe1-xSe1-delta (delta equals to 0.03-0.05 based on our neutron-diffraction ...
Nonstoichiometry of LixCu2O2+delta single crystal and its relation to magnetic ordering

Yeh, KW; Huang, TW; Ke, CT; Wu, PM; Zhao, L; Chao, WH; Lee, YC; ... (9 authors) (2010)

We report the first systematic study on the nonstoichiometry of Li/Cu ionic ratios x and oxygen defect concentrations delta in LixCu2O2+delta solid solution. Nonstoichiometric crystals with intentional Li-deficient (x=0.97) ...
