In-situ growth of superconducting SmO(1−x)F(x)FeAs thin films by pulsed laser deposition

Oxypnictide thin film growth by pulsed laser deposition (PLD) is one of many insufficiently resolved issues in the research of iron-based superconductors. Here we report on the successful realization of superconducting SmO(1−x)F(x)FeAs oxypnictide thin film growth by in-situ PLD on CaF(2) (fluorite)...

description Oxypnictide thin film growth by pulsed laser deposition (PLD) is one of many insufficiently resolved issues in the research of iron-based superconductors. Here we report on the successful realization of superconducting SmO(1−x)F(x)FeAs oxypnictide thin film growth by in-situ PLD on CaF(2) (fluorite) substrates. CaF(2) acts as fluorine supplier by diffusion and thus enables superconducting oxypnictide thin film growth by PLD. Films are grown heteroepitaxially and characteristically have a broad resistive normal-to-superconducting transition. Best films have onset transition temperatures around 40 K. The proposed in-situ PLD film growth offers an alternative and cheap route for the fabrication of iron oxypnictides. PLD becomes now an additional option for iron oxypnictide synthesis.
