摘要
The (57)Fe NMR spectra in yttrium iron garnets (YIG) containing low concentrations of the nontrivalent cations Ca(2+) and Si(4+) were measured. The analysis of the satellite structure caused by Si(4+) and Ca(2+) substitutions in the neighborhood of the resonating iron ion indicated that the spatial correlation of Si(4+) and Ca(2+) is small.
