摘要：
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 (001) with good crystallinity. The superconducting critical transition temperature (T-c) ranges from similar to 8 to similar to 10 K. The self-field critical current density (J(c)(sf)) at 4K is similar to 1.2 x 10(4) A/cm(2). The in-field critical current density (J(c)(in-field)) 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.
