Abstract / Bemerkung
We study current-induced deterministic magnetization switching and domain-wall motion via polar Kerr microscopy in all-amorphous W66Hf34/Co-Fe-B (CFB)/TaOx with perpendicular magnetic anisotropy and a large spin Hall angle. Investigations of magnetization switching as a function of the in-plane assist field and the current-pulse width yield switching-current densities as low as 3 x 10(9)A/m(2). We accredit this low switching-current density to a low depinning-current density, which is obtained from measurements of domain-wall displacements upon current injection. This correlation is verified by investigations of a Ta/CFB/MgO/Ta reference sample, which shows critical-current densities that are at least one order of magnitude larger.
