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

Wu, Phillip M. (AMER PHYSICAL SOC, 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 ...
Low temperature amorphization and superconductivity in FeSe single crystals at high pressures

Wu, Phillip M. (MATERIALS RESEARCH SOC, 2010)

In this study, we report low temperature x-ray diffraction studies combined with electrical resistance measurements on single crystals of iron-based layered superconductor FeSe to a temperature of 10 K and a pressure of ...
