NMR in the Earth's magnetic field

摘要

The development of NMR methods in high magnetic fields has opened the door to many applications in the last decades. A trend to higher magnetic fields produced by large and expensive superconducting magnets took place because the signal-to-noise ratio (S/N) and the dispersion of different NMR lines improve with increasing field strength. Parallel to the development of NMR in strong magnetic fields, the potential of NMR in low-magnetic fields (
