Interplay of geometrical and spin chiralities in 3D twisted magnetic ribbons.

ABSTRACT: Chirality is a ubiquitous and fundamental asymmetry in nature^1,2. Recently, the interaction of chiral objects with spin currents has attracted enormous attention from both scientific and technological perspectives^3-5. Of particular interest is the current-driven motion of chiral topological excitations such as chiral magnetic domain walls in chiral three-dimensional magnetic structures that could allow for high-density memory-storage devices. Here we use state-of-the-art multiphoton lithography^6,7 to create three-dimensional chiral magnetic ribbons and perform current-induced motion of chiral domain walls. The ribbons are designed to have a clockwise or anticlockwise chiral twist with a variable magnitude. We find that domain walls can either pass through t
