In Situ Ordering of FePt Thin Films by Using Ag / Si and Ag / Mn 3 Si / Ag / Si Templates

چکیده
In situ ordering of FePt thin films by sputtering onto Ag/Si and Ag/Mn3Si/Ag/Si templates has been demonstrated. Due to the evolution from island-like to a continuous film structure as a function of Ag thickness, the ordering and orientation of the FePt films both change with Ag thickness. A continuous (002) Ag film results in a greater L10 phase formation with -axis oriented both perpendicular to and in the film plane while the island-like Ag template results in less L10 phase formation, but a preferential -axis orientation in the film plane. On the other hand, the FePt films deposited onto the Ag/Mn3Si/Ag/Si template have their axes aligned perpendicular to the film plane.

The effects of Ag underlayer and Pt intermediate layers on the microstructure and magnetic properties of epitaxial FePt thin films
In this work, Ag underlayers, which have a slightly larger lattice parameter than FePt, were found not only to induce epitaxial growth of the FePt films but also to reduce the temperature at which the atomic ordering occurred. Without using the Ag underlayer, the FePt film deposited onto the hydrofluoric acid etched-Si substrate was FCC disordered. When Ag underlayers were used the FePt unit ce...

In this work Ag underlayers, with a slightly larger unit cell than FePt, were found not only to induce epitaxial growth of the FePt films but also to reduce the FePt ordering temperature. Without using the Ag underlayer, the FePt film deposited onto the Si substrate was fcc disordered. By the use of the Ag underlayer, it was observed that the FePt unit cells were expanded in the film plane. Thi...
متن کاملStructure and magnetic properties of SmCo thin films on Cr/Ag/Si templates
SmCo thin films were grown onto highly oriented Cr/Ag/Si templates of various orientations and their properties compared to those of SmCo/Cr/glass thin film structures. No conclusive evidence of local crystalline order in SmCo films was observed by microscopy techniques. However, in-plane uniaxial magnetic anisotropy was observed for SmCo films grown onto Si~111! and ~110! templates, indicating...
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 کاملEffects of Ru and Ag cap layers on microstructure and magnetic properties of FePt ultrathin films
The effects of Ru and Ag cap layers on the microstructure and magnetic properties of the FePt ultrathin films have been investigated. The results indicate that i) The Ag cap layer segregates from the FePt/Ag bilayer, lowers the FePt ordering temperature, promotes the FePt thin films to form island structure, and enhances the coercivity; ii) The Ru cap layer increases the FePt ordering temperatu...
