Abstract
From Mössbauer spectra of GdAlO3 and GdVO4 above and below the Néel temperature and fitted using a transmission integral, we have determined the following parameters of the 86.5 keV and 105 keV levels:g(86)/g(0)=+1.217±0.005,Q(86)/Q(0)= +0.10±0.02,g(105)/g(0)=−0.55±0.02,Q(105)/Q(0)=+0.74±0.02, Δ〈r 2〉105/ Δ〈r 2〉86=+1.30±0.05. The linewidth observed for the 105 keV transition is less than the calculated natural linewidth.
