Abstract

We report the fabrication of Nb-sheathed FeSe_0.5Te_0.5 superconducting tapes by the ex-situ powder-in-tube method. In our fabrications, high-quality FeSe_0.5Te_0.5 polycrystalline material was firstly employed as precursor and different annealing settings were performed on as-rolled FeSe_0.5Te_0.5 tapes as their last heat-treatment steps. Subsequently, resistance measurements and magnetization measurements were carried out on annealed FeSe_0.5Te_0.5 tapes. Furthermore, according to our results, the highest superconducting transition temperature and the highest self-field magnetic critical current density of our FeSe_0.5Te_0.5 tape reached about 15.7 K and 1 × 10⁴ A/cm² at 5 K, respectively.
