Effects of the rf current and bias field direction on the transition from linear to non-linear gyrotropic dynamics in magnetic vortex structures

Lakshmi Ramasubramanian, Vadym Iurchuk, Serhii Sorokin +2

We present a frequency-domain study of the dynamic behavior of a magnetic vortex core within a single Permalloy disk by means of electrical detection and micromagnetic simulations.…

Stress-induced modification of gyration dynamics in stacked double-vortex structures studied by micromagnetic simulations

Vadym Iurchuk, Attila Kákay, Alina M. Deac

In this paper, using micromagnetic simulations, we investigate the stress-induced frequency tunability of double-vortex nano-oscillators comprising magnetostrictive and non-magneto…
