Abstract

Abstract A high-temperature superconducting (HTS) coil, in which YBa2Cu3O7-δ is vapor-deposited on the surface of a sapphire plane, has been developed to increase signal-to-noise ratios (SNR) in solid-state nuclear magnetic resonance (NMR) measurements. The Q-factor of the NMR probe is found to be 16,125 at the resonant frequency of 38.525 MHz. A single sharp signal, full width at half maximum of 20 ppm, can be detected by the HTS coil in a stationary solid-state 79Br NMR spectrum of a polycrystalline potassium bromide at the temperature of 9 K. Compared with the results for an isomorphic copper coil, an improvement of a factor of 6.6 is obtained for SNR, indicating that accumulation time of NMR experiments can be reduced to 1/44.
