Broadening of the spectral line of spin self-oscillations in a nanocolumn magnetic structure upon magnetic field and current variations
The spin dynamics in a thin layer of a nanocolumn layered magnetic structure during the flow of a spin-polarized current in the presence of magnetic fluctuations is theoretically analyzed. Using the macrospin model, the frequency and Q factor of the spin oscillations are calculated as functions of the spin-polarized current upon the occurrence of current self-generation.
