Spin pumping by traveling magnetostatic surface waves (MSSW) has been experimentally investigated in YIG|Pt structures made on the basis of 0.9, 4, 8, 14 and 18 μm thick YIG epitaxial films. It is found that at frequencies corresponding to van Hove singularities density states MSSW spectrum structure, EMF value generated due inverse spin Hall effect increases. This increase associated with an m...

A balancing domain decomposition (BDD) method is considered as a preconditioner of the iterative domain decomposition method (DDM) for magnetostatic problems. The BDD method enables us to keep convergence properties of the iterative DDM even if the number of subdomains increases. However, in case of magnetostatic problems, the dimension of the coarse problem required in the BDD procedure depend...

Magnetic domain walls in ferromagnetic tracks can be used to trap and transport superparamagnetic beads for lab-on-a-chip applications. Here it is shown that the magnetostatic binding between a domain wall and a superparamagnetic bead suspended in a host fluid leads to a distinct magneto-mechanical resonance under application of a sinusoidal driving field. The characteristic resonant frequency ...

For the study of parametric excitation, we have considered that the origin of Stimulated Brillouin Scattering (SBS) nonlinear interaction lies in the third-order optical susceptibility in a centrosymmetric, doped semiconductor which is subjected to transverse magnetic field. The third-order optical polarization in a SBS system arises due to nonlinear current density and acousto-optical strain o...

Efficient numerical methods are required for the design of optimised devices. In magnonics, primary computational tool is micromagnetic simulations, which solve Landau-Lifshitz equation discretised in time and space. However, their cost high, complexity output hinders insight into physics simulated system, especially case multimode propagating wave-based We propose a finite-element modal method...

Existence of backward TE volume modes which are to be identified as Magnetostatic Wave (MSW) in anisotropic single-negative slab with partly negative permeability tensor component have already been revealed by present authors. In this paper, detailed modal analysis has been carried out for this kind of TE volume modes to find out their novel and peculiar properties. From these numerical results...

i.e., that the free currents flow in closed loops. Likewise, the time derivative of the fourth Maxwell equation implies that Jfree has no time dependence in magnetostatics. Often, magnetostatics is taken to be the situation in which ∇ · Jfree = 0 and D, E and Jfree have no time dependence, without explicit assumption that B and H also have no time dependence. Discuss the possibility of waves of...
