@article { , title = {Modification of perpendicular magnetic anisotropy and domain wall velocity in Pt/Co/Pt by voltage-induced strain}, abstract = {The perpendicular magnetic anisotropy Keff, magnetization reversal, and field-driven domain wall velocity in the creep regime are modified in Pt/Co(0.85–1.0 nm)/Pt thin films by strain applied via piezoelectric transducers. Keff, measured by the extraordinary Hall effect, is reduced by 10 kJ/m3 by tensile strain out-of-plane ez5931024, independently of the film thickness, indicating a dominant volume contribution to the magnetostriction. The same strain reduces the coercive field by 2–4 Oe, and increases the domain wall velocity measured by wide-field Kerr microscopy by 30-100\%, with larger changes observed for thicker Co layers. We consider how strain-induced changes in the perpendicular magnetic anisotropy can modify the coercive field and domain wall velocity.}, doi = {10.1038/srep07921}, eissn = {2045-2322}, journal = {Scientific Reports}, publicationstatus = {Published}, publisher = {Nature Publishing Group}, url = {https://nottingham-repository.worktribe.com/output/742899}, volume = {5}, year = {2015}, author = {Shepley, P.M. and Rushforth, A.W. and Wang, M. and Burnell, G. and Moore, T.A.} }
