Scalaron-driven Dark Matter during Warm Inflation via UV Freeze--in
F. Millo
We investigate the production of Dark Matter (DM) within the warm Higgs--Starobinsky (HS) inflation. By adopting the ultraviolet (UV) freeze--in mechanism -- where the DM number de…
Micromagnetic Modeling of Surface Acoustic Wave Driven Dynamics: Interplay of Strain, Magnetorotation, and Magnetic Anisotropy
Florian Millo, Pauline Rovillain, Massimiliano Marangolo +1
We study the coupling mechanism of surface acoustic waves (SAW) with spin waves (SW) using micromagnetic analysis. The SAW magnetoacoustic excitation field is fully implemented, i.…
Experimental observation of vortex gyrotropic mode excited by surface acoustic waves
R. Lopes Seeger, F. Millo, G. Soares +4
The traditional method for exciting spin-wave dynamics in magnetic materials involves microwave magnetic fields generated by current injection into inductive antennas. However, the…
Symmetry of the dissipation of surface acoustic waves by ferromagnetic resonance
Florian Millo, Rafael Lopes Seeger, Claude Chappert +2
We study the symmetry of the coupling between surface acoustic waves and ferromagnetic resonance in a thin magnetic film of CoFeB deposited on top of a piezoelectric Z-cut LiNbO3 s…
