Originální abstrakt

Magnetic vortices have been an interesting element in the past decades due to their flux-closure domain structures which can be stabilized at ground states in soft ferromagnetic microstructures. In this work, vortex states are shown to be nucleated and stabilized in Fe80Ga20 and Fe70Ga30 disks, which can be upcoming candidate for applications in strain-induced electric field control of magnetic states owing the high magnetostriction of the alloy. The magnetization reversal in the disks occurs by the formation vortex, double vortex or S-domain state. Micromagnetic simulations have been performed using the FeGa material parameters and the simulated magnetic states are in good agreement with the experi-mental results. The studies performed here can be essential for the use of FeGa alloy in low-power electronics.& COPY; 2023 Vietnam National University, Hanoi. Published by Elsevier B.V.
