Single passage NMRON and the spin-temperature question

  • P. J. Back
  • G. A. Stewart


The analysis of spin-lattice relaxation (SLR) of very dilute impurity nuclei in ferromagnetic hosts, as encountered in NMR of oriented nuclei (NMRON), usually neglects the spin-spin interaction, assuming a no-spin-temperature model. However, the regime of impurity systems for which this assumption is valid has not been established. the relaxation following single passage in60CoFe<110> and55CoFe<100> has been measured, and is compared with calculations made with and without a spin-temperature constraint.
