Abstract
Adiabatic Fast Passage NMR/ON measurements on single crystal56CoFe indicate a unique electric field gradient when the applied field is parallel to the 〈100〉 direction.
A well defined spin echo has been observed with pulsed NMR/ON using the 847 keV gamma and the echo amplitude decay followed for pulse separations out to 75 ms. The decay of the echo is non exponential, being essentially constant for pulse separations of 75 μs, 750 μs and 7.5 ms. The echo is significantly attenuated at 75 ms. This may be contrasted with an effective nuclear spin lattice relaxation time of T ′1 ∼30 s.
