What is it about?
NMR experiments in pulsed high magnetic fields have been a challenge as the magnetic fields can be generated only a short period of time with the pulse field technology. We overcome this issue by using a feedback control of pulse fields and a versatile software defined radio (SDR) technology. These advanced technologies enable NMR measurement in pulse fields in almost the same way as in the conventional steady fields, thus open a possibility to measure microscopic physical properties at extreme magnetic fields.

Why is it important?
Our NMR spectrometer with pulse-field magnet enables the NMR measurements in extreme magnetic field that breaks the limitation of magnetic field strength in a steady condition. NMR in high fields is important because such a high magnetic field introduces fascinating quantum states in a material but their origin cannot be elucidated by conventional physical properties measurements, such as resistance and magnetization measurements. NMR measurements is a powerful probe to explore the microscopic parameters that determine the physical properties of materials. We can adopt our spectrometer for high-field measurement and make a significant advance in the understanding of fundamental quantum mechanics.
Perspectives
Pulse-field technology has been an attractive but difficult thing as we need to visit large magnetic field facility to conduct measurements in pulse fields. Our development enables a measurements in extremely high fields using these facilities and at the same time enables high field measurements in a small laboratory using a compact instruments. This feature will allow many researchers to access high fields that were difficult to achieve with conventional steady fields and contributes to discover novel quantum states in magnetic fields.
