Keywords:
iron-based superconductor CaKFe4As4,c-axis textured superconducting bulk,critical current properties
Since iron-based superconductors have potential for high-field applications, we have developed superconducting bulk samples using 1144-type material CaKFe4As4. In this study, using the Spark Plasma Sintering (SPT) technique, which is the combination of Spark Plasma Sintering (SPS) method and hot working method, we have successfully synthesized a CaKFe4As4 bulk sample with c-axis textured. Here we report the critical current properties of the bulk and discuss the determining factors in comparison with the results of microstructure observations and chemical composition analysis.
