Spin waves in Co2FeGe films
The dynamic magnetic properties of full Heusler alloy thin films of Co2FeGe, grown on MgO (001) substrates under different thermal conditions, were investigated. Brillouin light scattering and ferromagnetic resonance measurements revealed that depositing at room temperature followed by annealing at 300 °C for 1 h produces the best results for maximizing magnetization, exchange stiffness, and minimizing spin-dynamic dissipation in the films, which are desirable characteristics for high-speed spintronic devices. Additionally, strong hybridization of spin waves in the Damon–Eshbach geometry was observed, which is attractive for applications in magnonic signal processing circuits.
