Abstract

Hydrogen absorption effects in the R2Fe17 series of alloys have been established from pressure-composition (pc) isotherms, crystal structure determination and magnetic measurements. If no plateau pressure has been observed in the (pc)-isotherms, such curves have been found to be dependent on the nature of the R element. The results agree with a progressive but successive filling of the octahedral 2R-4Fe and the tetrahedral 2R-2Fe sites. Most of the modifications observed in the magnetic properties can be correlated with changes in selected Fe-Fe distances.
