摘要	It is shown that the superconductivity in Ce1-xGdxFeAsO0.84F0.16 compounds can be modulated by internal (chemical) pressure. The internal pressure is induced by Gd substitution for Ce in CeFeAsO0.84F0.16, which compresses the crystal lattice. The temperature dependences of resistivity and magnetization show that the superconducting-transition temperature T-c is enhanced from 40 K for CeFeAsO0.84F0.16 to 47.5 K for Ce0.6Gd0.4FeAsO0.84F0.16. The increase and subsequent decrease of Tc upon application of external pressure, as observed previously in LaFeAsO0.89F0.11, is entirely confirmed by the modulation of Tc of the Ce1-xGdxFeAsO0.84F0.16 superconductors by internal pressure.
