- 論文の詳細を見る
The electronic properties of an oxypnictide, LaFeAsO, pressurized in a diamond-anvil cell, were investigated by 57Fe Mössbauer spectroscopy and electrical resistance measurements at pressures up to 24 and 35 GPa, respectively. The Néel temperature gradually decreased from ${\sim}140$ K at 0.1 MPa to ${\sim}50$ K at 20 GPa, and fell below 8 K or disappeared at 24 GPa. The hyperfine field at 8 K decreased from 5.3 T at 0.1 MPa to 2.2 T at 20 GPa. On the other hand, the onset of superconductivity occurred at ${\sim}9$ K at 2 GPa. The superconductivity peaked at ${\sim}21$ K at 12 GPa, and then began a perceptible decline, disappearing at ${\sim}35$ GPa. This suggests that suppression of antiferromagnetic order plays an important role in the emergence of pressure-induced superconductivity.
