In situ ordered polycrystalline FePt L10 „001... nanostructured films and the effect of CrMn and Zn top layer diffusion
The nanostructure and magnetic properties of in situ ordered polycrystalline FePt thin films ~9 nm! have been studied. Films were deposited with a MgO underlayer onto Si and glass substrates using conventional rf diode sputtering. Perpendicular anisotropy was obtained when the substrate temperature exceeded 490 °C. The maximum order parameter ~S! was estimated to be ;0.9. The coercivities (Hc) ...
متن کاملSize-Dependent Chemical and Magnetic Ordering in L10-FePt Nanoparticles
FePt nanoparticles have great application potential in advanced magnetic materials such as ultrahigh-density recording media and high-performance permanent magnets. The key for applications is the very high uniaxial magnetocrystalline anisotropy of the L10-FePt phase, which is based on crystalline ordering of the face-centered tetragonal (fct) structure, described by the chemical-ordering param...
متن کاملChemical ordering phenomena in nanostructured FePt: Monte Carlo simulations.
Free-surface-induced L10 chemical long-range ordering phenomena in a nanolayer, a nanowire and a cubic nanoparticle of FePt were studied by means of Monte Carlo simulations. The system was modeled with nearest-neighbor and next-nearest-neighbor interatomic pair interactions deduced from ab initio calculations. The generated samples, the dimensionality of which was determined by appropriate peri...
متن کاملDirect synthesis of partially ordered tetragonally structured FePt nanoparticles by polyol method for biomedical application
We report the direct soft chemical synthesis and characterization of a family of face centered cubic (fcc) and partially ordered face centered tetragonal (fct) FePt nanoparticles (NPs) suitable for biomedical applications. Both fcc and partially ordered fct-FePt NPs are synthesized by employing a simple polyol method. By using polyvinyl pyrolidone (PVP) as a stabilizer in various ratios during ...
