The author studied the effect of chemical compound for superconducting performance ($$J$$c) of iron-based superconductors. As a result, it was revealed that BaFe$$_{2}$$As$$_{2}$$ showed high Jc. And more, BaFe$$_{2}$$As$$_{2}$$ showed higer $$J$$c such as 32,000A/cm$$^{2}$$ (4.2K) by being applied of 120 MPa of hot isostatic pressure (HIP). Thus, higher $$J$$c performance could be achieved.

We demonstrate a large enhancement of critical current density ($$J$$$$_{rm c}$$) up to 1.0 $$times$$ 10$$^{7}$$ A/cm$$^{2}$$ at 5 K under self-field in (Ba,K)Fe$$_{2}$$As$$_{2}$$ single crystals by irradiating 320 MeV Au ions. With the very promising potential of this material in mind, we have fabricated a (Ba,K)Fe$$_{2}$$As$$_{2}$$ superconducting wire through a powder-in-tube method combined with the hot isostatic pressing technique, whose effectiveness has been proven in industrial Bi2223 tapes. The Jc in the wire at 4.2 K has reached 37 kA/cm$$^{2}$$ under self-field and 3.0 kA/cm$$^{2}$$ at 90 kOe. Magneto-optical imaging of the wire confirmed the large intergranular Jc in the wire core.
