3D nanomagnetism concerns the investigation of nanoscale magnetic materials and phenomena in three dimensions, which offer a rich playground for fundamental physics, with higher degrees of freedom, new topologies and geometries combining to produce new effects. These range from emergent chirality and complex energy landscapes to topological textures that occur on nanometre length scales, encompassing systems like top-down and bottom-up engineered 3D nanostructures, heterostructures and magnetic metamaterials.

3DMAG 2026 will be the first edition of this international symposium devoted to 3D nanomagnetism. The event aims to bring together this vibrant, rapidly growing multidisciplinary community, to discuss the challenges and opportunities of expanding nanomagnetism into the third dimension. To foster community and encourage interaction, the conference will be held in a single-session format featuring invited and contributed talks. Ample time will be allocated for discussions, networking, poster sessions, round tables, and social activities.

Focus topics of the conference will include: nanofabrication, characterisation, and modelling of 3D magnetic systems, spin topology in 3D, physical phenomena, such as frustration and fluctuations in 3D, new 3D architectures, effects resulting from the interplay of bulk, surface and curvature, magnetization dynamics and excitations in 3D, spintronics in 3D, and applications of 3D nanomagnetism in, for example, sensing, storage, unconventional computing,  and related nanotechnology fields, e.g., bio-magnetism.

The conference will be held in the heart of Vienna, the capital of Austria, a city renowned for its rich history in art, music, and science.
