Reversal of coupled vortices in advanced spintronics: A mechanistic study

Autor: Hamadeh, A., Koujok, A., Perna, S., Rodrigues, D. R., Riveros, A., Lomakin, V., Finocchio, G., de Loubens, G., Klein, O., Pirro, P.

This study conducts a comprehensive investigation into the reversal mechanism of magnetic vortex cores in a nanopillar system composed of two coupled ferromagnetic dots under zero magnetic field conditions. The research employs a combination of exper

Current-induced self-sustained magnetization oscillations in spin-torque nano-oscillators (STNOs) are promising candidates for ultra-agile microwave sources or detectors. While usually STNOs behave as a monochrome source, we report here clear bimodal

We experimentally demonstrate tight focusing of a spin wave beam excited in extended nanometer-thick films of Yttrium Iron Garnet by a simple microscopic antenna functioning as a single-slit near-field lens. We show that the focal distance and the mi
