摘要: Magnetization and57Fe Mossbauer measurements were carried out on RFe12−xVxNy compounds (R=Y and Nd,x=1.7 2.2) the effects of nitrogen vanadium atoms the57Fe hyperfine fields at different iron crystallographic sites investigated. The field decreases with increasing number neighbour all sites. is strongly enhanced in composition withy>1 where compound tends to transform into an amorphous-like solid. moment deduced from increases more upon nitrogenation for 8i-site than other sites, exceeds bcc iron.
