Abstract
The heavy metal/ferromagnet type MgO/CoFeB/Ta structure with in-plane magnetization and high spin polarization was studied. We use the adiabatic harmonic Hall voltage method to study the effective damping coefficient and to estimate the values of the effective fields that arise in such structures under the action of a spin-polarized current.
