Structure and Exchange Anisotropy of Evaporated Ni-Fe/Mn-(Ni-Fe) Films.

Exchange anisotropy in PtMn / Ni 80 Fe 20 films on MgO ( 1 1 0 )

For the first time, we successfully developed exchange anisotropy of PtMn/Ni80Fe20 (1 1 0) bilayers grown on a MgO(1 1 0) substrate with or without Pt buffer layer. The results of angular-dependent magneto-optical Kerr effect indicate that the PtMn/Ni80Fe20(1 1 0) films possess unidirectional anisotropy with coercivity and exchange field around 135Oe and 60Oe, respectively. The Pt buffer layer ...

Surface morphology, structure and magnetic anisotropy in epitaxial Ni films

Understanding the correlation between film structure and its ferromagnetic properties is very important for applications. To this end, we have investigated epitaxial and smooth Ni films grown on MgO substrates using molecular beam epitaxy (MBE) and dc sputtering. To establish correlation between film morphology and structure with magnetic properties, we have used in situ and ex situ scanning tu...

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, ...

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...
