Disorder-sensitive superconductivity in the iron silicide LuFeSi studied by the Lu-site substitutions
T. Watanabe, H. Sasame, H. Okuyama +2
We studied effect of non-magnetic and magnetic impurities on superconductivity in LuFeSi by small amount substitution of the Lu site, which investigated structural, mag…
Successive phase transitions under high pressure in FeTe0.92
Hironari Okada, Hiroyuki Takahashi, Yoshikazu Mizuguchi +2
We performed magnetization and electrical resistivity measurements under high pressures of up to 19 GPa for FeTe0.92. The compound shows an anomaly in magnetization and resistivity…
75As-NMR studies on La FeAsO1-xFx (x=0.14) under a pressure of 3GPa
K. Tatsumi, N. Fujiwara, H. Okada +4
75As-nuclear magnetic resonance (NMR) on an iron-based superconductor LaFeAsO1-xFx (x=0.14) was performed under a pressure of 3GPa. Enhancement of superconducting transition temper…
Pressure-induced superconductivity in Iron pnictide compound SrFe2As2
K. Igawa, H. Okada, H. Takahashi +6
Electrical resistivity under high pressure have been measured on nominally pure SrFe2As2 up to 14 GPa. The resistivity drop appeared with increasing pressure, and we clearly observ…
