Abstract
Nuclear orientation and NMR measurements on 131I nuclei implanted in Fe single crystals have been compared with a simplified theory of the magnetisation behavior of the single crystals. It is shown that both the angular distribution and the resonance frequency as a function of an external magnetic field can be described reasonably with this model. Additionally, a clear difference between the zero-field resonance frequency in single crystals and that in polycrystalline samples is observed.
