Structural and magnetic phase transformations in the diluted laves phases Pr(Fe1 − xAlx)2

The Pr(Fe1 − x Al x )2 alloys with concentrations x = 0–1 have been synthesized under a high pressure. The phase composition and lattice parameters (a and c) have been determined as a function of x. The magnetic and Mossbauer measurements have been performed at T = 90–400 K. It has been established that the Curie temperatures of alloys linearly depend on their composition.
