Development of Cylindrical Resonator for Millimeter-Wave Band ESR/NMR Double Magnetic Resonance

Year: 2025

Type: article

Abstract: We have developed a magnetic resonance equipment for very low temperature and high magnetic field aiming at Dynamic Nuclear Polarization-Nuclear Magnetic Resonance (DNP-NMR) and Electron-Nuclear DOuble Resonance (ENDOR) of diluted spin system using with Electron Spin Resonance (ESR). In this study, we have developed a cylindrical resonator with a submicron-thick gold film for millimeter-wave band ESR/NMR double magnetic resonance by exploiting frequency dependence of skin depth. ESR measurements were performed using the fabricated resonator at around 130 GHz and in the temperature range of 3 K to 70 K of BDPA diluted to 100 mM in polystyrene. ESR sensitivity is obtained from the measurement. 19 F-NMR signal from the sample holder is also successfully observed.
