文摘

Average distances of Fe–Fe (d(Fe–Fe)) were calculated using lattice constants. Hyperfine fields (IF) in Fe sites were measured using Mössbauer spectroscopy. Relationship between d(Fe–Fe) and IF at each Fe site was obtained. Co substitution and N introduction effects on IF was also measured. Magneto-volume effect is main reason of IF augmentation in Fe sites.
