Our laboratory develops new superconducting materials in intermetallic compounds and transition metal oxides. 

Superconducting materials are used in applications such as maglev trains and medical MRI systems. In maglev trains, for instance, the property of zero electrical resistance is utilized to create powerful electromagnets, generating the immense force needed to levitate and propel the vehicle. However, the superconducting transition temperature (TC) of the superconductors actually employed in these applications is by no means high (approximately 9 K or -264°C). 

Materials in a superconducting state require cryogen to keep extremely low temperature, which entails significant costs; consequently, it is easy to see that a higher superconducting transition temperature (TC) is advantageous for practical applications. Furthermore, ease of fabrication—such as into wires—and resistance to magnetic fields are crucial factors for application. Therefore, our laboratory focuses on developing new superconducting materials that exhibit high TC and high critical field, particularly utilizing intermetallic compounds that are easily bent or stretched.
