Researchers at Tokyo Metropolitan University have developed a new superconducting material by combining iron, nickel, and zirconium. This novel transition metal zirconide displays superconducting characteristics, despite neither iron zirconide nor nickel zirconide individually being superconducting. The new material exhibits a "dome-shaped" phase diagram, indicating potential for high-temperature superconducting applications. The study suggests that magnetic elements play a key role in unconventional superconductivity, potentially paving the way for practical developments in next-generation superconducting technologies.
