“…1, C and D) becomes parallel or antiparallel to the polarization of the surface and thus the asymmetric spin wave propagation between ±k can be expected. Such a surface-induced spin wave nonreciprocity has first been predicted by Damon and Eshbach more than 50 years ago [9], and then verified by various experimental techniques such as spin wave spectroscopy [10,11], spin-polarized electron energy loss spectroscopy [12], thermography [13], and Brillouin light scattering [14]. In particular, the k → 0 mode mediated by the magnetic dipole-dipole interaction in this configuration is called magnetostatic surface wave (representing that it can propagate only at the surface of the sample), and is known for its unidirectional propagation character [9,11,15].…”

Spin current, i.e. the flow of spin angular momentum or magnetic moment, has recently attracted much attention as the promising alternative for charge current with better energy efficiency. Genuine spin current is generally carried by the spin wave (propagating spin precession) in insulating ferromagnets, and should hold the chiral symmetry when it propagates along the spin direction. Here, we experimentally demonstrate that such a spin wave spin current (SWSC) shows nonreciprocal propagation characters in a chirallattice ferromagnet. This phenomenon originates from the interference of chirality between the SWSC and crystal-lattice, which is mediated by the relativistic spin-orbit interaction.The present finding enables the design of perfect spin current diode, and highlights the importance of the chiral aspect in SWSC.

“…Several calculation methods have been developed in the past. [18][19][20][21][22][23][24][25] In the 1970s and 1980s, PSWS was used extensively in insulating yttrium iron garnet ͑YIG͒ films 18,26,27 which, due to their ultralow microwave losses, enable propagation of spin waves over several millimeters. In the calculations, the losses in the ferromagnetic material were ignored and the only parameter which was calculated is the radiation resistance of the excitation antenna.…”

Spin-wave transduction at the submicrometer scale: Experiment and modeling

We report a complete study of spin-wave transduction combining microwave measurements performed over a frequency range of ͓1-15͔ GHz on Permalloy strips ͑thickness= 10-20 nm, width=2-8 m͒ and an accurate modeling of the experiment. This technique has been used recently to assess the spin polarization of the electrical current by measuring a current-induced spin-wave Doppler shift. We present here an electromagnetism calculation based on the magnetostatic wave theory combined with the Gilbert form of the damping that can be used directly as an optimization tool for future spin-wave experiments.

“…1-3 Especially, the spatially modulated spin configuration stabilized in the patterned ferromagnetic nanostructures is known to excite the non-uniform coherent spin precession with a spatial periodical modulation, namely, spin wave. [4][5][6][7] Owing to its fast time scale in GHz range and high compatibility with a Si-based semiconductor integrated circuits, the spin waves in ferromagnetic thin films are expected to have various potential applications in future telecommunication devices, such as a microwave filter, 8-10 oscillator, [11][12][13] and fast spin-information transportation. 14,15 In addition, the development of high-performance spin-based telecommunication devices also makes an innovation in military and security applications.…”

We have investigated the stability for the resonant spin precession under the strong microwave magnetic field by a specially developed detection method using the anisotropic magnetoresistance effect. The electrically separated excitation and detection circuits enable us to investigate the influence of the heating effect and the nonuniform spin dynamics independently. The large detecting current is found to induce the field shift of the resonant spectra because of the Joule heating. From the microwave power dependence, we found that the linear response regime for the standing spin wave is larger than that for the ferromagnetic resonance. This robust characteristic of the standing spin wave is an important advantage for the high power operation of the spin-wave device. V C 2015 AIP Publishing LLC. [http://dx.
