Abstract
Here we report the enhanced superconductivity in the LaFeAsO1−xFx system prepared by high pressure synthesis. The highest onset superconducting transition temperature ( T c ) in this La-based system is 41.0 K with the nominal composition of LaFeAsO1−xFx ( x = 0.6 ), which is higher than that reported previously by ambient pressure synthesis. The increase of T c can be attributed to further shrinkage of the crystal lattice that causes stronger chemical pressure on the Fe–As plane, which is induced by the increased F-doping level under the high pressure synthesis.
