Abstract: The effect of La addition in Fe-P-N upon Snoek-Ke-Kster(SKK)damping peak was studied.It was found that the damping depends on the atomic concentration ratio between La and P(C_(La)/C_P).When the ratio is comparatively high in the alloy(for example,4.56 on 2.6),La will appreciably enhance SKK damping,whereas in the alloy saturated with P at a lower C_(La)/C_P ratio of 0.27 La will no longer exert any effect on SKK peak.

Key words: Internal friction, SKK peak, Fe-P-La-N alloy
