Abstract
The magnetic structure of a Pt3Fe alloy changes from antiferromagnetic to ferromagnetic as a result of plastic deformation. The recovery processes of the magnetic transition have been studied in a Pt3Fe alloy deformed plastically by 36% strain. Three recovery processes have been discovered; the spontaneous magnetization decreases in 473 K and 673 K annealing and disappears in 1073 K annealing. Each recovery process is discussed from the viewpoint of the atomic migration and the dislocation displacement through the activation process.Keywords
