➀ Researchers have developed a high-temperature superconducting (HTS) wire with a current-carrying capacity 50% higher than the previous record holder, without increasing manufacturing costs or complexity. ➁ The new HTS wire, based on rare-earth barium copper oxide (REBCO), achieves a critical current density and pinning force at all magnetic field strengths and temperatures from 5K to 77K. ➂ This breakthrough could revolutionize the application of superconductors in various fields, including power grids, magnetic levitation trains, and medical MRI scanners.
