Outline of Final Research Achievements |
We have developed new spectrometer of nuclear magnetic resonance (NMR) for pulsed high fields. This spectrometer allows us to measure NMR spectrum and relaxation rate (NMR-T1) in the flat-top pulsed magnetic fields of up to 60 Tasla, which is generated with PID controlled small electromagnet inserted in main electromagnet.

Academic Significance and Societal Importance of the Research Achievements |
パルス強磁場は極めて高い磁場を実現する唯一の方法であり、これまでNMR測定が難しかった強磁場中の物性を明らかにするために活用されることが期待される。また、超伝導磁石は導入費用・維持費が高額であるが、パルス磁場で同程度の磁場を出す場合は非常に安価であり、そういった安価な磁場発生手法でNMR測定ができるようになったという点も意義深い。
