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.<br />Comment: 5 pages, 4 figures. Figure 1 is now separated into Fig. 1 and Fig. 2 to separate piston-cylinder and anvil pressure techniques. Updated reference list. Modified Fig. 4
