Abstract:
The preference site and magnetic property of doped Cr atom in L1 0 FePt alloy are investigated by the first-principles calculations. Due to the energy of Cr located in Fe and Pt sublattice are -0.15 and 0.48 eV, respectively, the Cr atom occupying Fe site is more energetic favorable than in Pt site in L1 0 FePt alloy. The calculated saturation magnetizations for Cr additive replacing Fe or Pt atom in L1 0 FePt are 959 or 989 emu/cm 3 , respectively. The results are lower than that of L1 0 FePt (1085emu/cm 3 ). The additive of Cr in L1 0 FePt will reduce the saturation magnetization.
