Fine control of L10 ordering and grain growth kinetics by C doping in FePt films
We present the results on highly anisotropic oriented face-centered-tetragonal ordered equiatomic FePt thin films embedded in a C matrix prepared by cosputtering technique on MgO ~100! substrates at 400 °C. We have found that doping of C in FePt alloy films is an effective and appropriate way to control the L10 ordering and growth of grain size down to 4 nm. Room-temperature magnetic measuremen...
متن کاملModulation of preferred orientation and easy axis of magnetic anisotropy in L10 FePt films with Cu buffer layers
The crystallographic orientation and easy axis of magnetic anisotropy in L10 FePt films were successfully modulated with Cu buffer layers. The FePt film directly grown on the Cr90Mo10 underlayer showed a (001) preferred orientation with out-of-plane magnetic anisotropy. As the Cu buffer layer thickness was z4 nm, the FePt films showed a (110) preferred orientation with in-plane magnetic anisotr...
متن کاملL 10 ordering and microstructure of FePt thin films with Cu , Ag , and Au additive
The influence of Cu, Ag, and Au additives on the L10 ordering, texture, and grain size of FePt thin films has been examined. Lattice parameter data indicated that Au and Ag additives tended to segregate from FePt, but Cu alloyed with FePt. FePt films with Au or Ag additive showed 1–2 kOe higher coercivity values compared to a pure FePt film after annealing at 450 °C and above for 10 min. The ad...
متن کاملThickness and Growth Temperature Dependence of Structure and Magnetism in FePt Thin Films Michael F. Toney[a], Wen-Yaung Lee[b], Jonathan A. Hedstrom and Andrew Kellock
We describe structural and magnetic measurements of polycrystalline, L10 chemical-ordered Fe(55-60)Pt(45-40) lms as a function of lm thickness (from 3 to 13 nm) and growth temperature (270 370 C). With increasing lm thickness, the coercivity increases from about 1 kOe up to 11 kOe (growth at 400C), while for increasing growth temperature, the coercivity grows from 0.2 to 6 kOe for 4.3 nm thick ...
متن کاملImprovement of Magnetic Properties and Texture of FePt Thin Films on MgO Substrates by Sn Addition
In this work, we studied the effects of Sn addition on the ordering temperature of FePt thin film. The coercivity of FePtSn film was about 1000 Oe greater than the coercivity of FePt film for an annealing temperature of 600C. Therefore, Sn addition was effective in promoting the L10 ordering and in reducing the ordering temperature of the FePt film. From our X-ray diffraction results, we found ...
