Abstract

Pressure dependence on superconducting transition temperature (T c) has been investigated for iron-based superconductor LaFeAsO 1-xFx, SmFeAsO1-xFx and Ca(Fe 1-xCox)AsF. The Tc increases largely for LaFeAsO1-xFx with a small increase of pressure, and decreases with further compression. In SmFeAsO1-xFx the Tc decreases with increasing pressure. The increase of Tc in LaFeAsO1-xFx seems to be related to the suppression of magnetic ordering phase. Pressure-induced superconductivity was observed for these materials. The common features on 1111 type superconductors are discussed.
