Abstract

Spin transfer nano-oscillators are microwave devices based on two major spintronic physical phenomena: spin transfer effect and magnetoresistive effect. These spintronic oscillators are possibly new type of integrated devices for applications such as microwave emission, frequency modulation, frequency mixing and frequency detection. In order to reach telecommunication applications required specifications, several issues must be tackled such as operating conditions without a magnetic field and phase noise reduction. Here we investigate experimentally how two different types of spin transfer oscillators based on magnetic vortex core dynamics might be a solution to address these issues.
