Influence of the Inverse Faraday Effect on Switching and Oscillations of Magnetization in Single-Domain Nanoparticles

摘要

We have performed a numerical simulation of magnetization switching and oscillations in a ferromagneticudsingle-domain particle in the disk form under the influence of nanosecond laser pulses with linearudand circular polarization. The analysis has shown that the interaction of laser pulses with a ferromagneticudnanodisk leads to change in the direction of its magnetization. This process is accompanied by magnetizationudoscillations with duration from units to tens of nanoseconds. As it follows from the obtained results,udthe main cause of magnetization switching is the reduction of magnetic anisotropy energy at heating of theudstructure by laser. The field of the inverse Faraday effect can lead to an increase in frequency and amplitudeudof this oscillations.When you are citing the document, use the following link http://essuir.sumdu.edu.ua/handle/123456789/24926
