FeCoB Films with Large Saturation Magnetization and High Magnetic Anisotropy Field to Attain High Ferromagnetic Resonance Frequency

High-Frequency Behavior and Damping of Fe–Co–N-Based High-Saturation Soft Magnetic Films

Magnetization dynamics measurements at subnanosecond time scale have been performed on Fe–Co–N high-saturation soft magnetic films with Permalloy nanolayer seeds and having a saturation magnetization of 1.9 MA/m (1900 emu/cm). The damping parameter varies from 0.011 to 0.018, depending on applied bias field. The peak frequencies of the imaginary permeability spectra and the zero-crossing freque...

Light–induced magnetization reversal of high-anisotropy TbCo alloy films

Magnetization reversal in nanoscale magnetic films with perpendicular anisotropy.

Stress dependence of soft, high moment and nanocrystalline FeCoB films

Soft, high moment materials are crucial for the magnetic data recording industry in applications such as write poles and soft underlayers. Ever increasing areal densities have pushed the requirements for materials exhibiting saturation magnetizations above 2 T. In this work we investigate nanocrystalline FeCoB which exhibits a saturation magnetization of ;2.2 T. FeCoB exhibits a magnetostrictio...

Perpendicular magnetic anisotropy and magnetization dynamics in oxidized CoFeAl films

Half-metallic Co-based full-Heusler alloys with perpendicular magnetic anisotropy (PMA), such as Co2FeAl in contact with MgO, are receiving increased attention recently due to its full spin polarization for high density memory applications. However, the PMA induced by MgO interface can only be realized for very thin magnetic layers (usually below 1.3 nm), which would have strong adverse effects...
