Ferromagnetic resonance of a magnetostatically stabilized domain wall in a nanowire–nanoparticle planar system

Resumo

The results of micromagnetic simulation of induced high-frequency magnetization oscillations in a planar ferromagnetic system composed of a magnetostatically coupled nanowire and nanoparticle are reported. The possibility of transformation of the spectrum of this system by introducing a domain wall stabilized with the magnetic field of the nanoparticle into the nanowire is discussed. The dependences of the frequency and amplitude of resonant oscillations of the domain wall on the geometric parameters of the system are analyzed.
