TL;DR: The article moves on to consider how non-linear optical techniques and post-processing solutions can be used to realise structures with a feature size below 100 nm, before comparing two-photon lithography with other direct write methodologies and providing a discussion on future developments.
Journal ArticleDOI
Magnetic Charge Propagation upon a 3D Artificial Spin-ice
TL;DR: A 3D artificial spin-ice is detailed, which captures the exact geometry of bulk systems, allowing magnetic charge dynamics to be directly visualized upon the surface.
Journal ArticleDOI
Use of Two-Photon Lithography with a Negative Resist and Processing to Realise Cylindrical Magnetic Nanowires
TL;DR: This work provides a new means to realize 3D magnetic nanowires of controlled geometry and calculations suggest a further reduction in diameter to sub-200 nm will be possible, providing access to a regime of ultrafast domain wall motion.
Journal ArticleDOI
Magnetic charge propagation upon a 3D artificial spin-ice
TL;DR: In this paper, a 3D artificial spin-ice is presented, which captures the exact geometry of bulk systems, allowing magnetic charge dynamics to be directly visualized upon the surface.
Journal ArticleDOI
Asymmetric dual Bloch point domain walls in cylindrical magnetic nanowires
TL;DR: The asymmetric dual Bloch point wall (ADBPW) as discussed by the authors has surface vortices similar to an asymmetric transverse wall and two Bloch-point textures adjacent to the internal vortex tube.
