Note: Commercial SQUID magnetometer-compatible NMR probe and its application for studying a quantum magnet

Abstract: We present a compact nuclear magnetic resonance (NMR) probe which is compatible with a magnet of a commercial superconducting quantum interference device magnetometer and demonstrate its application to the study of a quantum magnet. We employ trimmer chip capacitors to construct an NMR tank circuit for low temperature measurements. Using a magnetic insulator MoOPO with S = 1/2 (Mo) as an example, we show that the T-dependence of the circuit is weak enough to allow the ligand-ion NMR study of magnetic systems. … Show more

“…10 Thus, spatial resolution is a key factor limiting the magnetoencephalography images and an important indicator for the measurement system. 11 Nitrogen-vacancy diamond magnetometers 12 and atomic magnetometers (AMs) based on ultracold atoms 13 are ideally suited for high-resolution mapping with smaller probing volumes, but the operating frequency is in the range of radio frequency. The current magnetoencephalography (MEG) system mainly adopts spin-exchange relaxation-free (SERF) AM 14,15 and superconducting quantum interferometer (SQUID) magnetometer 16 operating at low frequency.…”

“…Especially in the field of brain science, 9 it is necessary to explore the functional structure of the brain and to trace the location of neurological diseases with a high‐sensitivity magnetometer array 10 .
