| Tailoring the chirality of magnetic domain walls by interface engineering |
| Speaker: | Dr. Andreas Schmid (NCEM, Lawrence Berkeley National Laboratory, Berkeley/California 94720, USA) |
| Abstract: | The rich physics of chiral spin textures includes strongly asymmetric response of left-handed versus right-handed spin structures under applied current, and extremely high domain wall mobility in response to very low critical current density [1,2]. These properties make chiral magnetic materials promising candidates for the development of new spintronics applications. How one might control the magnetic chirality of domain walls and change it between right-handed, left-handed, or achiral, has remained a key question in this field.
Using spin-polarized low energy electron microscopy, we found a new type of chiral domain wall structure in perpendicularly magnetized systems [3]. Moreover, we discovered that subtle adjustment of a non-magnetic spacer layer allows us to tailor the chirality of magnetic [Co/Ni]n multilayers. By introducing magnetic chirality as a new degree of freedom, this f |
