Abstract
A spin oscillator device including a first spin Hall effect nano-oscillator, SHNO, having an extended multilayered magnetic thin-film stack, wherein a nano-constriction, NC, is provided in the magnetic film stack providing an SHNO including a magnetic free-layer and a spin Hall effect layer, and having a nanoscopic region, wherein the NC is configured to focus electric current to the nanoscopic region, configured to generate the necessary current densities needed to excite magnetization auto-oscillations, MAO, in the magnetic free layer, wherein a circumferential magnetic field surrounds the NC, wherein an externally applied field with a substantial out-of-plane component is configured to control the spatial extension of the MAO towards a second spin oscillator device, which is arranged in MAO communication and synchronized to the first NC.
