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

The magnetostatic modes in planar one-dimensional magnonic crystals with nanoscale sizes

Autor: M. L. Sokolovskyy, Maciej Krawczyk

Publikováno v: Journal of Nanoparticle Research

The plane-wave method is used to determine the spin-wave spectra in nanoscale one-dimensional magnonic crystals formed by a periodic lattice of ferromagnetic stripes. The dynamic demagnetizing field in a new formulation is used in these calculations.

Physical Review B

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 impact of the lattice symmetry and the inclusion shape on the spectrum of 2D magnonic crystals

Publikováno v: Journal of Applied Physics

We investigate spin waves in two-dimensional superlattices in the form of an infinite ferromagnetic slab of finite thickness with periodically embedded ferromagnetic inclusions. One of the reasons of the interest in magnonic superlattices is the poss

We present an all-optical time-resolved measurement of dipole-exchange spin wave spectra in a series of CoO capped [Co(t)/Pt(7 A)]n-1 Co(t) multilayer systems, where the total Co moment (n × t) is constant. In general, the spectra consist of two int
