The influence of plastic deformation on the antiferromagnetic ordering in a chemically ordered FePt3 alloy
Magnetic susceptibility was measured in a plastically deformed 25.6 at.% Fe-Pt single crystal. The susceptibility decreases considerably for 1.3% strain and at the same time spontaneous magnetisation appears. On cooling, the spontaneous magnetisation increases rapidly near the Neel temperatures. Fe atoms at the irregular sites induced by plastic deformation exert a destructive influence on magnetic ordering at distances as great as 103 AA. They enhance the magnetic exchange interaction of neighbouring Fe atoms at the regular sites and change them to ferromagnetic near the Neel temperatures.
