摘要：

A structural and magnetic characterization of R2Fe17 alloys and their corresponding hydrides has been carried out by means of powder neutron diffraction. The hydrides have been found to retain the host metal symmetry. Hydrogen is accommodated in rare-earth-rich octahedral and tetrahedral sites. The effects of hydrogenation on the magnetic properties are discussed. © 1990.
