First performance test of FeSe0.5Te0.5 coated conductor coil under high magnetic fields

Abstract Iron-based superconductors (IBS) have attracted intense interest from scientists around the world. The first FeSe0.5Te0.5 hybrid coil including one single pancake (SPC) and eight YBCO double coils (DPCs) was successfully fabricated test in this study. tape used is encapsulated strengthen which with 0.15 mm thickness 10.5 width to withstand high stress during cold test. exhibits good performance at 4.2 K DPCs were divided into two groups connected both sides of SPC. critical current measured under background field increased 0 T 10 T. transport SPC showed 108.1 A self-field 17.4 T, had almost same as short sample. results study that coated conductor magnetic fields.
