Control and Optimization of Coherence of a Nano-Sized Spin-Torque Microwave Oscillator for Military Nano-Electronics

Abstract

Passage of an electric current through a multilayered magnetic nano structure can lead to the excitation of a persistent magnetization precession in the thinner ("free") magnetic layer of the structure. The frequency of the excited auto oscillations is close to the ferromagnetic resonance frequency and typically lies in the microwave frequency range. This effect can be used for the development of a novel class of fully metallic microwave nano sized oscillators - spin-torque oscillators (STO).
