Effects of magnetostatic coupling on stripe domain structures in magnetic multilayers with perpendicular anisotropy" (2007). We investigate the effects of magnetostatic interlayer coupling on the formation of magnetic domains in exchange-coupled ferromagnetic films exhibiting perpendicular magnetic anisotropy. Using simple models for the stripe domain structures we investigate how the magnetost...

Surface (plasmon) resonances or electrostatic surface modes are possible on an interface between two materials with permittivity of opposite signs, and interfaces with permeability of opposite signs can support similar magnetostatic surface modes. This paper contains a review of the possible surface modes in several canonical geometries, and also numerical results demonstrating the importance o...

A fully self-consistent model for the excitation and reception of magnetostatic surface waves in thin ferromagnetic films by a set coplanar antennas was developed implemented numerically. The assumes that film is highly conducting interfaced with non-magnetic metallic films, but also suitable modeling magneto-insulating films. Perpendicular magnetic anisotropy Dzyaloshinskii-Moriya interaction ...

Spin-wave dynamics in full-Heusler Co2FeAl0.5Si0.5 films are studied using all-optical pump-probe magneto-optical polar Kerr spectroscopy. Backward volume magnetostatic spin-wave (BVMSW) mode is observed in films with thickness ranging from 20 to 100 nm besides perpendicular standing spin-wave (PSSW) mode, and found to be excited more efficiently than the PSSW mode. The field dependence of the ...

When a strong magnetostatic field is present, vacuum effectively appears as a linear, uniaxial, dielectric–magnetic medium for small–magnitude optical fields. The availability of the frequency–domain dyadic Green function when the magnetostatic field is spatially uniform facilitates the formulation of an integral equation for the scattering of an optical field by a spatially varying magnetostat...

in this paper, scattering of a plane and monochromatic electromagnetic wave from a nano-wire is simulated using surface integral equations. first, integral equationsgoverning unknown fields on the surface is obtained based on stratton-cho surface integral equations. then, the interaction of the wave with a non-plasmonic as well as a palsmonic nano-wire is considered. it is shown that in scatter...
