Abstract
Satellite structure in 57Fe NMR spectra of
In3+ , Sc3+ ,
Ga3+ and Al3+ substituted yttrium
iron garnets (YIG) was analysed taking into account results previously
obtained for ‘antisit’ defects (Y3+ ions on
Fe3+ sites) in nominally pure YIG. The influences of the
diamagnetic substitution on the hyperfine field at the neighbouring iron
nuclei were found to be remarkably dependent on the ionic radius of the
substituent. In the case of two substituents in the vicinity of the resonating
iron, an additivity of their effects within a 15% tolerance interval
was verified.
