ABSTRACT
We describe a dc superconducting quantum interference device (SQUID) based magnetic resonance spectrometer particularly suited to measurements in the frequency range of 100 kHz to several megahertz. Results are presented for nuclear quadrupole resonance (NQR) of boron-11 in boron nitride at 4.2 K, yielding ω[sub Q] = 1467 ± 2 kHz. We also present a direct measurement of the methyl group tunneling frequency, ω[sub t] = 210 ± 10 kHz, of propionic acid in low field, at 4.2 K.
