Nitrogen and hydrogen absorptions have been carried out in order to discuss the influence of interstitial atoms on the magnetovolume effects for the La(Fe xAl 1-x) 13 (x=0.83 and 0.86) compounds. The average magnetic hyperfine field and the Curie temperature T C of nitrides are lower than that of hydrides. The volume expansion due to the nitrogen absorption is about twice that due to the hydrogen absorption. Comparing the change in T C of the nitrides with that of hydrides and the pressure effect on T C, the hybridization between the Fe 3d and N 2p orbital should be taken into consideration in the lower T C of nitrides.
