N2  - 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 &#8216;antisit&#8217; 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.
