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…
Superconductivity under high pressure in LaFeAsO
H. Okada, K. Igawa, H. Takahashi +5
Electrical resistivity measurements under high pressures up to 29 GPa were performed for oxypnictide compound LaFeAsO. We found a pressure-induced superconductivity in LaFeAsO. The…
Pressure Study of Superconducting Oxypnictide LaFePO
K. Igawa, H. Okada, K. Arii +6
Electrical resistivity and magnetic susceptibility measurements under high pressure were performed on an iron-based superconductor LaFePO. A steep increase in superconducting trans…
