Abstract

The structure, Curie temperature, and magnetostriction of Sm1-xPrxFe2alloys have been investigated using optical microscopy, x-ray diffraction, ac susceptibility, diffractometer step scanning and standard strain gauge techniques. It is found that the matrix of homogenized Sm1-xPrxFe2 alloys is the (Sm,Pr)Fe-2 phase with MgCu2-type structure up tox=0.3, and the minor phases, both (Sm,Pr)Fe-3, and rare earth-rich phase appear. The lattice parameter of the alloys increases slowly with increasing Pr content, but the Curie temperature goes the opposite way. The room temperature magnetostriction \lambda(parallel to)-lambda(perpendicular to)\ and easy direction magnetostriction \lambda(111)\ of Sm1-xPrxFe2 alloys exhibit a peak near x=0.1.
