摘要
We have studied the structural and superconducting properties of the compound LaFeAsO0.9F0.1 under pressures up to 32 GPa using synchrotron radiation and diamond anvil cells. We obtain an ambient pressure bulk modulus K-0=78(2) GPa compressibility comparable to some cuprates. At high pressures, the sample is in the overdoped region, with a linear decrease with pressure variation of the superconducting transition temperature.
