Magnetic Surface Anisotropy in Ferromagnetic Thin Films with Two Rough Surfaces
نویسنده
چکیده
Abstract In this paper the magnetostatic energy in a ferromagnetic thin film with two imperfect, rough surfaces has been calculated. It has been shown that the surface roughness gives in some cases a considerable contribution to an effective perpendicular anisotropy. Within the model assumed it has been proved that the value of magnetostatic energy and, as a consequence, the anisotropy in a thin imperfect film does not depend on the relative location of the two rough surfaces.

Reduced Models for Ferromagnetic Thin Films with Periodic Surface Roughness
We investigate the influence of periodic surface roughness in thin ferromagnetic films on shape anisotropy and magnetization behavior inside the ferromagnet. Starting from the full micromagnetic energy and using methods of homogenization and [Formula: see text]-convergence, we derive a two-dimensional local reduced model. Investigation of this model provides an insight into the formation mechan...
متن کاملSpin-Wave Resonance Model of Surface Pinning in Ferromagnetic Semiconductor (Ga,Mn)As Thin Films
The source of spin-wave resonance (SWR) in thin films of the ferromagnetic semiconductor (Ga,Mn)As is still under debate: does SWR stem from the surface anisotropy (in which case the surface inhomogeneity (SI) model would apply), or does it originate in the bulk inhomogeneity of the magnetic structure of the sample (and thus requires the use of the volume inhomogeneity (VI) model)? This paper o...
متن کاملDirect surface charging and alkali-metal doping for tuning the interlayer magnetic order in planar nanostructures
The continuous reduction of magnetic units to ultrasmall length scales inspires efforts to look for a suitable means of controlling magnetic states. In this study, we show two surface charge alteration techniques for tuning the interlayer exchange coupling of ferromagnetic layers separated by paramagnetic spacers. Our ab initio study reveals that already a modest amount of extra charge can swit...
متن کاملOn the reorientation transition of ultra–thin Ni/Cu(001) films
The reorientation transition of themagnetization of ferromagnetic films is studied on amicroscopic basis within aHeisenberg spinmodel. Using a modified mean field formulation it is possible to calculate properties of magnetic thin films with non–integer thicknesses. This is especially important for the reorientation transition in Ni/Cu(001), as there the magnetic properties are a sensitive func...
متن کاملMagnetic and structural properties of epitaxial Fe thin films on GaAs(0 0 1) and interfaces
Fe(0 0 1) thin films (70 ( A) with Fe(7.2 ( A) tracer layers at the interface were epitaxially grown on GaAs(4 6) surfaces. Magneto-optic Kerr effect and Ferromagnetic resonance measurements indicate a dominant 2-fold in-plane magnetic anisotropy (easy axis along [1 1 0]) superimposed to a 4-fold anisotropy, and small coercivity (B10Oe). M . ossbauer (CEMS) measurements indicate no magnetic ‘‘d...
