Strain-induced modulation of perpendicular magnetic anisotropy in Ta/CoFeB/MgO structures investigated by ferromagnetic resonance.

The article presents a study focusing on strain-induced modulation of perpendicular magnetic anisotropy (PMA) in tantalum(Ta)/cobalt iron boron (CoFeB)/magnesium oxide (MgO) structures investigated by ferromagnetic resonance. The findings include strain-induced change in PMA extracted from the experimental ferromagnetic resonance (FMR) spectra, modulation of the PMA of an ultrathin CoFeB layer by voltage-induced strain and dependence of the effective damping constant as a function of strain.
