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…

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…

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…
