Abstract: The Pr(Fe$_{1-x}$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 Mössbauer measurements have been performed at $T$ = 90–400 K. It has been established that the Curie temperatures of alloys linearly depend on their composition.
