Abstract

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.
