Local non-linear excitation of sub-100 nm bulk-type spin waves by edge-localized spin waves in magnetic films

Magnetic vortex core reversal by excitation of spin waves

Micron-sized magnetic platelets in the flux-closed vortex state are characterized by an in-plane curling magnetization and a nanometer-sized perpendicularly magnetized vortex core. Having the simplest non-trivial configuration, these objects are of general interest to micromagnetics and may offer new routes for spintronics applications. Essential progress in the understanding of nonlinear vorte...

Excitation of coherent propagating spin waves by pure spin currents.

Utilization of pure spin currents not accompanied by the flow of electrical charge provides unprecedented opportunities for the emerging technologies based on the electron's spin degree of freedom, such as spintronics and magnonics. It was recently shown that pure spin currents can be used to excite coherent magnetization dynamics in magnetic nanostructures. However, because of the intrinsic no...

Observation of propagating edge spin waves modes

Spin Waves along the Edge States

Spin waves (SWs) have been studied experimentally and by simulations in 1000 nm side equilateral triangular Permalloy dots in the Buckle state (B, with in-plane ̄eld along the triangle base) and the Y state (Y, with in-plane ̄eld perpendicular to the base). The excess of exchange energy at the triangles edges creates channels that allow e®ective spin wave propagation along the edges in the B stat...

Spectrum and Attenuation of Non-Linear Surface Magnetostatic Spin Waves in Ferrite Films

Dispersion and attenuation of non-linear surface magnetostatic waves (MSSW) propagating in thin ythium-irongarnet (YIG) fenite Nms have been studied both experimentally and theoretically. They were defined from the amplitude and phase alterations of the wave as it traveled along the "non-equilibrium" part of the film. At the border of such a non-equilibrium part the wave power is equal to the t...
