Layering and temperature-dependent magnetization and anisotropy of naturally produced Ni/NiO multilayers

Engineering magnetic anisotropy and magnetization switching in multilayers by strain.

The effect of the strain on the magnetic properties of metallic multilayers has been investigated by ab initio studies. Our results indicate that the magnetic anisotropy energy (MAE) of an Fe(001) surface can be drastically enhanced by capping with 5d elements. By choosing Ir-Fe multilayers as a model system, we demonstrate that the MAE which depends on the composition and the structure of the ...

Magnetization and ordering temperature of films and multilayers

We investigate, in this paper, a number of magnetic properties of single and multilayer thin film systems within the Ising model by application of mean field, finite cluster approximations as well as by Monte Carlo simulations. The magnetization profiles and the magnetic ordering temperature are calculated for different magnetic systems. The influence of corrugation and disorder at the surface,...

Temperature-dependent interface magnetism and magnetization reversal in Co/Pt multilayers

Sources of interface magnetization and interface anisotropy in Fe/Cu multilayers as revealed by thermal behavior

Sources on interface magnetization and anisotropy in Fe/Cu multilayers have been investigated via thermal behavior using DC magnetization and ferromagnetic resonance techniques. The samples were prepared by DC sputtering resulting in equal thickness elemental layers ranging in modulation wavelength from 1 to 30 nm. The interface anisotropy remains nearly constant at 0.32 erg/cm2 through the tem...

Magnetization in quasiperiodic magnetic multilayers with biquadratic exchange and uniaxial anisotropy

A theoretical study is made of the magnetization versus applied field curves of ferromagnetic/nonmagnetic multilayers constructed according to a Fibonacci quasiperiodic sequence. The ferromagnetic films are assumed to have uniaxial anisotropy and are coupled by both bilinear and biquadratic effective exchange. The effects of quasiperiodicity in the magnetic phases are illustrated numerically fo...
