Abstract
Superconducting FeSe0.5Te0.5 thin films are deposited on amorphous substrates, i.e., glass substrates by a pulsed laser deposition (PLD) technique. Microstructural characterizations show that the films are highly textured along (00l) with good crystallinity. The superconducting critical transition temperature (Tc) ranges from ∼8 to ∼10 K. The self-field critical current density (Jcsf) at 4 K is ∼1.2×104 A/cm2. The in-field critical current density (Jcinfield) decreases slowly under high magnetic field confirmed by both transport and magnetization measurements. The growth of high quality superconducting FeSe0.5Te0.5 thin films on amorphous substrates demonstrates a low cost architecture for future Fe-based superconductor coated conductors.
