Abstract

We present X-ray diffraction and selected-area-electron diffraction and fluorescence measurements of (Pr80Ga20)100-xFex amorphous alloys for 0 ≤ x ≤ 30. Partial pair-distributions were determined and compared with calculations based on a random-occupation model. The results show that the atomic distribution is not random. The selected-area electron diffraction and fluorescence results for x {greater-than or approximate} 20 show the presence of a separationinto Fe-rich and Fe-poor glassy phases. This phase separation plays an important role in the magnetic properties of these alloys.
