Buffer layer engineering of L1₀ FePd thin films with large perpendicular magnetic anisotropy

Perpendicular magnetic anisotropy in chemically disordered FePd–FeV„100... alloy thin films

We find that the use of V 100 buffer layers on MgO 001 substrates for the epitaxy of FePd binary alloys yields to the formation at intermediate and high deposition temperatures of a FePd–FeV mixed phase due to strong V diffusion accompanied by a loss of layer continuity and strong increase of its mosaic spread. Contrary to what is usually found in this kind of systems, these mixed phase structu...

Nanostructured FePt:B2O3 thin films with perpendicular magnetic anisotropy

Domain-wall scattering in epitaxial FePd ordered alloy films with perpendicular magnetic anisotropy

Domain-wall scattering in a FePd-ordered alloy film with strong perpendicular magnetic anisotropy has been investigated using magnetoresistance measurements on a whole hysteresis loop and as a function of temperature. A strong correlation between the hysteretic behavior of the resistivity due to domain walls and the magnetization process is found. The data are well described by a spin-dependent...

Temperature and thickness dependence at the onset of perpendicular magnetic anisotropy in FePd thin films sputtered on MgO„001..

The onset of chemical order L10 phase and perpendicular magnetic anisotropy in FePd 001 thin films sputtered on MgO 001 at temperatures from room temperature to 700 °C and thickness between 1.4 and 22 nm are investigated. It is found that the formation of the FePd ordered phase exhibiting high perpendicular magnetic anisotropy L10 phase with the c axis in the growth direction is affected by a t...

Spin–orbit torque-assisted switching in magnetic insulator thin films with perpendicular magnetic anisotropy

As an in-plane charge current flows in a heavy metal film with spin-orbit coupling, it produces a torque on and thereby switches the magnetization in a neighbouring ferromagnetic metal film. Such spin-orbit torque (SOT)-induced switching has been studied extensively in recent years and has shown higher efficiency than switching using conventional spin-transfer torque. Here we report the SOT-ass...
