Abstract: K39.00006 : Enhancement of spin-motive force in systems with broken inversion symmetry*
9:24 AM–9:36 AM
The experimentally observed SMFs thus far are typically 100nV-1μV. To achieve larger SMF is deemed indispensable towards realization of spintronic devices actively exploiting SMF. In this work we address this problem demonstrating that, in the presence of Dzyaloshinskii-Moriya Interaction (DMI), the SMF due to field-induced domain-wall motion can be dramatically enhanced. The presence of DMI leads to extra spatial rotation of the magnetization, which turns out to play a crucial role in the enhancement of SMF. Our results suggest a new perspective on inversion-symmetry-broken systems as a suitable stage for pursuit of larger SMF.
