Creation of uni-directional spin-wave emitters by utilizing interfacial Dzyaloshinskii-Moriya interaction
Thomas Brächer, Philipp Pirro, Olivier Boulle +1
We present an analytic and numerical study of the creation of an uni-directional spin-wave emission in ultra-thin ferromagnetic films sandwiched in an asymmetric layer stack. For t…
Controlling Dzyaloshinskii-Moriya Interaction via Chirality Dependent Layer Stacking, Insulator Capping and Electric Field
Hongxin Yang, Olivier Boulle, Vincent Cros +2
Using first-principle calculations, we demonstrate several approaches to manipulate Dzyaloshinskii-Moriya Interaction (DMI) in ultrathin magnetic films. First, we find that DMI is…
Room temperature chiral magnetic skyrmion in ultrathin magnetic nanostructures
Olivier Boulle, Jan Vogel, Hongxin Yang +16
Magnetic skyrmions are chiral spin structures with a whirling configuration. Their topological properties, nanometer size and the fact that they can be moved by small current densi…
