We have successfully demonstrated electrical charging using the electromotive force (EMF) generated in a ferromagnetic metal (FM) film under resonance (FMR). In case of Ni80Fe20 films, charge due to EMF FMR can be accumulated capacitor; however, amount is saturated well below limit capacitor. Meanwhile, Co50Fe50, capacitor and increases linearly with duration time. The difference between Co50Fe...

With the development of new nanofabrication technologies and measurement techniques, interest researchers is moving toward 3D structures magnetization textures. Special attention paid to topological textures, particularly hopfions. In this paper, we investigate dynamics hopfion through numerical solution eigenvalue problem. We show that spectrum spin-wave modes much richer than those attainable...

We demonstrate spatial resolution of ferromagnetic resonance in a microscopic sample of YIG using ferromagnetic resonance force microscopy ~FMRFM!. Measurements were performed on a small single crystal YIG film grown on a GGG substrate, roughly rectangular in shape 20 mm3;150 mm and 3 mm thick. The perpendicular and parallel force geometries of FMRFM, in conjunction with an external bias field ...
