H NMR in pulsed magnets
The trend towards higher static magnetic fields, B0, in
NMR is driven not only by the higher signal-to-noise
and chemical shift resolution attainable, but also by the
desire to study systems with markedly field-dependent
properties which may only be observable at very high B0
values. Examples include field-induced phase transitions
[1], strongly correlated electron systems, magnetic
materials, powders with large quadrupole interactions,
and molecular alignment due to anisotropic magnetic
susceptibility [2].
Commercial 21.14 T (900 MHz) high-resolution
superconducting magnets have become available in the
past two years. The National High Magnetic Field
Laboratory (NHMFL) at Tallahassee has reported the
design of an ultra-wide bore (105 mm diameter)
900 MHz magnet [3]. The highest field produced by a
