Magnetic and structural properties of Y/sub 6-x/Er/sub x/Fe23 alloys and their hydrides
Description
The magnetic characteristics and structural features of the Y/sub 6-x/Er/sub x/Fe23 alloys and their hydrides are reported. The parent alloys all formed in a face-centered cubic structure. A pronounced minimum in the lattice parameter was observed for Er4Y2Fe23. A similar minimum was also observed in the 1 atm hydrogen capacity of the alloys. The hydrides of the Y-rich compounds were found to retain the cubic structure of the parent compounds, whereas the hydrides of Er5YFe23 and Er6Fe23 adopt tetragonally distorted structures. Both the intermetallics and their hydrides were observed to be ferrimagnetic, exchange-dominated systems. In all cases, absorption of hydrogen resulted in an increase in both the saturation magnetization and the Curie temperature
