Electric field control of domain wall propagation in Pt/Co/GdOx films
نویسندگان
چکیده
The influence of a gate voltage on domain wall (DW) propagation is investigated in ultrathin Pt/Co/gadolinium oxide (GdOx) films with perpendicular magnetic anisotropy. The DW propagation field can be enhanced or retarded by an electric field at the Co/GdOx interface and scales linearly with gate voltage up to moderate bias levels. Higher gate voltage levels, corresponding to electric fields >0.2V/nm, produce a large irreversible change to the magnetic anisotropy that can enable nonvolatile switching of the coercivity.VC 2012 American Institute of Physics.

Interfacial current-induced torques in Pt/Co/GdOx
Current-driven domain wall (DW) motion is investigated in Pt/Co/GdOx nanostrips with perpendicular magnetic anisotropy. Measurements of the propagation field and the energy barrier for thermally activated DW motion reveal a large current-induced torque equivalent to an out-of-plane magnetic field of 60 Oe per 10 A/m. This same field-to-current scaling is shown to hold in both the slow thermally...
متن کاملFast propagation of weakly pinned domain walls and current-assisted magnetization reversal in He+-irradiated Pt/Co/Pt nanotracks
Magnetic-domain-wall propagation is experimentally studied in nanotracks etched in ultrathin Pt/Co/Pt films with out-of-plane magnetic anisotropy, where pinning has been artificially reduced by low-dose He-irradiation. Fast domainwall propagation is demonstrated in such tracks under low magnetic fields, not greater than the fields necessary to make a domain wall propagate in the He-irradiated p...
متن کاملVelocity asymmetry of Dzyaloshinskii domain walls in the creep and flow regimes.
We have carried out measurements of domain wall dynamics in a Pt/Co/GdOx(t) wedge sample with perpendicular magnetic anisotropy. When driven by an easy-axis field Hz in the presence of an in-plane field Hx, the domain wall propagation is different along [Formula: see text]x, as expected for samples presenting Dzyaloshinskii-Moriya (DMI) interaction. In the creep regime, the sign and the value o...
متن کاملMagnetic relaxation measurements of exchange biased (Pt/Co) multilayers with perpendicular anisotropy
Magnetic relaxation measurements were carried out by magneto-optical Kerr effect on exchange biased (Pt/Co)5/Pt/FeMn multilayers with perpendicular anisotropy. In these films the coercivity and the exchange bias field vary with Pt spacer thickness, and have a maximum for 0.2 nm. Hysteresis loops do not reveal important differences between the reversal for ascending and descending fields. Relaxa...
متن کاملStructural and magnetic depth profiles of magneto-ionic heterostructures beyond the interface limit
Electric field control of magnetism provides a promising route towards ultralow power information storage and sensor technologies. The effects of magneto-ionic motion have been prominently featured in the modification of interface characteristics. Here, we demonstrate magnetoelectric coupling moderated by voltage-driven oxygen migration beyond the interface in relatively thick AlOx/GdOx/Co(15 n...
