The oscillation frequency is 11.6 GHz, which is significantly higher than the modulation bandwidth of less than 4 GHz in the device. The oscillation frequency is determined by an additional resonance frequency in birefringence containing microcavities, which is potentially much higher than the conventional relaxation oscillation frequency. The damping of the oscillations can be controlled by the current, allowing for oscillation lifetimes much longer than the spin lifetime in the device as well as for short bursts potentially interesting for information transmission.</jats:p>"}],"user_id":"15911","department":[{"_id":"977"}],"_id":"59692","language":[{"iso":"eng"}],"issue":"15","publication_status":"published","publication_identifier":{"issn":["0003-6951","1077-3118"]},"citation":{"chicago":"Gerhardt, N.
