Abstract
The synthesis and magnetic properties of Pr{sub x}Ce{sub 1-x}Fe{sub 2} have been investigated. The formation of Pr{sub x}Ce{sub 1-x}Fe{sub 2} is found to depend strongly on annealing temperature. Pure single-phase compound can be synthesized at ambient pressure when x{<=}0.5. The main phase of the Laves structure can still be observed up to x=0.8. The study of crystalline parameters, magnetic moments and Moessbauer spectra for single-phase Pr{sub x}Ce{sub 1-x}Fe{sub 2} is performed. Curie temperature and local Fe magnetic moment increase with the increasing Pr concentration. Extrapolating the trends the spontaneous magnetization and anisotropy constant of PrFe{sub 2} are 4.98 {mu}{sub B} fu{sup -1} and 7.3x10{sup 5} J m{sup -3} at 1.5 K, respectively. Magnetostriction increases with increasing x and the largest saturation magnetostriction, 200 ppm, is observed for x=0.5. With the increase of Pr concentration, lattice parameter and spontaneous magnetization anomalies exist in a specific range 0.2<x<0.5 that can be attributed to the change of Ce ion valence toward tetravalent.
