H NMR at 2.4 GHz in a pulsed high-field magnet
The inherent diamagnetic response of superconduc-
tors limits their use in applications such as producing
very-high-strength magnets. With classical superconduc-
tors, the high-field limit for persistent-mode magnets is
currently only 22 T [1]. New high-temperature super-
conductors can sustain much higher fields but only with
substantial losses that make them less promising for
high-stability applications. Therefore, resistive magnets
[2] or hybrids of superconducting and resistive magnets
are increasingly being employed for high-field applica-
tions, including NMR. However, not only do such
systems have a much poorer stability than is required for
higher-resolution NMR, they also have tremendously
high associated installation and operation costs. Mag-
netic fields as high as 45 T have been reached using
hybrids [3]. However, a significant increase in field
