Search for pressure induced superconductivity in CeFeAsO and CeFePO iron pnictides
arXiv:1011.1593 · doi:10.1103/PhysRevB.83.094528
Abstract
The CeFeAsO and CeFePO iron pnictide compounds were studied via electrical transport measurements under high-pressure. In CeFeAsO polycrystals, the magnetic phases involving the Fe and Ce ions coexist up to 15 GPa, with no signs of pressure-induced superconductivity up to 50 GPa. For the CeFePO single crystals, pressure stabilizes the Kondo screening of the Ce 4f-electron magnetic moments.
