摘要: Abstract The microstructure and magnetic properties of sputtered Fe-Pt thin films were studied as a function Pt content from 0 to 60 at%. Polycrystalline ferromagnetic obtained in the range studied. A mixture body-centered-cubic disorder face-centered-cubic (γ) phases was for as-deposited with less than 22 at% Pt, face-entered-cubic structure more 33 Pt. By annealing containing about coercivity 13 kOe could be depending on duration temperature annealing. An order faced-centered tetragonal (γ 1 ) phase appeared under suitable treatment samples 50 For comprising made deteriorate owing formation an antiferromagnetic (fcc, Ll 2 -type). X-ray analysis observations revealed that hardening caused by changing ordering γ phase.
