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...

Abstract In this paper the magnetostatic energy in a ferromagnetic thin film with two imperfect, rough surfaces has been calculated. It has been shown that the surface roughness gives in some cases a considerable contribution to an effective perpendicular anisotropy. Within the model assumed it has been proved that the value of magnetostatic energy and, as a consequence, the anisotropy in a thi...

a simple new closed form of the green function for axisymmetric magnetostatic problemsis found analytically in cylindrical coordinates. the result is verified by applying several examples.

Two wireless, passive remote query magnetism-based glucose sensors, which operate in combination with a mass and volume changing glucose responsive polymer, are presented. One sensor design is based upon the magnetostatic coupling of magnetically soft thin-film elements; as the polymer volume changes in response to glucose concentration so does the magnetostatic coupling between elements. In re...

A detailed study of the Counter-Rotating Model (CRM) for generic electrostatic (magnetostatic) axially symmetric thin disks without radial pressure is presented. We find a general constraint over the counter-rotating tangential velocities needed to cast the surface energy-momentum tensor of the disk as the superposition of two counter-rotating charged dust fluids. We then show that this constra...

Ab&act-The dispersion relation for wave propagation in a homogeneous, electrically neutral electron gas subject to crossed static electric and magnetic fields is derived using the coupled Maxwell-Boltzmann-Vlasov equations. The cutoff condition for transverse circularly polarized electromagnetic waves is obtained from the derived dispersion relation. The variation of the cutoff frequency CO,, w...

Lock-in thermography measurements were performed to reveal heat source distribution induced by the unidirectional spin-wave conveyer effect (USHCE) of magnetostatic surface spin waves. When waves are excited in an yttrium iron garnet slab, lock-in images show spatially biased sharp and complicated heating patterns, indicating importance edge dynamics for USHCE. The accessibility local emission ...

We present an experimental study of ultrafast optical excitation magnetostatic surface spin wave (MSSW) packets and their spectral properties in thin films pure iron. As the leave area propagate space, spectra evolve non-trivially. Particularly, low or high frequency components are suppressed at border depending on orientation external magnetic field with respect to magnetocrystalline anisotrop...

We analyze the spectrum of a certain singular integral operator on the space (L2(fi))3 where fi is contained in three dimensional Euclidean space and has a Lipschitz continuous boundary. This operator arises in the integral formulation of the magnetostatic field problem. We decompose (L2(fi))3 into invariant subspaces: in one where the operator is the zero map; in one, the identity map; and in ...
