The one-dimensional planar magnonic crystals are usually fabricated as a sequence of stripes intentionally or accidentally separated by non-magnetic spacers. The influence of spacers on shaping the spin wave spectra is complex and still not completel

We report spin wave excitations in a nanopatterned antidot lattice fabricated from a 30-nm thick Ni 80 Fe 20 film. The 250-nm-wide circular holes are arranged in a rhombic unit cell with a lattice constant of 400 nm. By Brillouin light scattering, we

The calculation of the magnonic spectra using the plane-wave method has limitations, the origin of which lies in the formulation of the effective magnetic field term in the equation of motion (the Landau-Lifshitz equation) for composite media. Accord

Publikováno v: Journal of Applied Physics

Planar one-dimensional magnonic crystals of nanoscale lattice constant having different types of overlayers, dielectric and metallic, are studied. The dynamics of magnetization is described by the Landau-Lifshitz equation, which is solved using the p

A possibility to observe huge lateral shift (Goos-Hanchen effect) of exchange spin wave reflected from the interface of two ferromagnetic materials is theoretically investigated. The strong dependence of this effect on the exchange coupling between t
