Structure and Saturation Magnetization for fct Fe-Ni-N Films.

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...

Magnetization Of Sm-Fe-N Thin Films With In-Plane Anisotropy

Am-Fe-N films have been made by dc magnetron sputtering and heating in-situ in nitrogen atmosphere. It is observed that the anisotropy changes from perpendicular to in-plane by nitrogenation. The Curie temperature is about 380 K. Aspects of structure, hysterisis loops, initial magnetization curves and temperature dependence of coercivity are discussed. SQUID magnetometer was used to measure the...

Structure, ferromagnetic resonance, and permeability of nanogranular Fe–Co–B–Ni films

Interface structure and surface morphology of (Co, Fe, Ni)/Cu/Si(100) thin films

We have examined bilayer Co/Cu, Fe/Cu, and Ni/Cu films deposited by molecular-beam epitaxy on hydrogen-terminated @100# silicon substrates. The magnetic metal/copper interface was examined by atomic resolution transmission electron microscopy and compared with the surface morphology as depicted by atomic force microscopy. The general orientation relationships across the magnetic metal/copper in...

Microscopic structure of Fe-Ni and Fe-Ni-S molten alloys of geophysical interest

The static S(Q) liquid structure factors for binary FexNi12x , x50.90, 0.85, and ternary Fe0.85Ni0.05S0.15 molten alloys are investigated by means of the concurrent use of neutron diffraction and reverse Monte Carlo simulations. The measured G(r) radial distributions reveal atomic orderings varying from that present in the Fe0.90Ni0.10 alloy, reminiscent of the ideal bcc structure of solid Fe, ...
