Structural and magnetic properties of Y(Al1−xFex)12

Abstract
In order to investigate the magnetic behavior of 3d atoms in the ThMn12‐type structure, the structured and magnetic properties of Y(Al1−xFex)12 were studied by Mössbauer spectroscopy and magnetization measurements. The Y(Al1−xFex)12 intermetallic compounds crystallize in the ThMn12‐type structure for x in the range of 0.3–0.5. The results can be explained on the basis of the preferential atomic ordering observed in the ternary compounds. The compounds are ferromagnetic with Curie temperatures of 130, 170, and 280 K, respectively, for x values of 0.3, 0.4, and 0.5.
