International Workshop on Magnetic Nanowires and Nanotubes, 2022

The 2021 edition of the International Workshop on Magnetic Nanowires and Tubes (IWMNT 2021) will take place on August 30 to September 3 2021 in Waischenfeld (Germany). This edition follows previous successful workshops held in Kaub am Rhein (12-15 May 2013) and Meersburg (17-20 May 2015).

Magnetic nanowires are now a mature topic. Although it started more than three decades ago, it thrives more than ever with new synthesis directions including tubes, core-shell and other three-dimensional designs, and an increasing number of investigations and functions revealed in single elements. Close connections exist with emerging topics such as 3D and curvilinear nanomagnetism and 3D spintronics. These research directions provide both opportunities for new frontiers of knowledge and potential for disruptive devices exploiting the third dimension of space. While these topics are present at international conferences, they rely by nature on an interdisciplinary effort involving various communities from chemists to experimental and theoretical physicists, who often do not have the opportunity to meet directly.

The aim of IWMNT is to provide a common meeting point for all scientists involved in the research and applications of magnetic nanowires, nanotubes, and more generally 3D magnetic architectures. The workshop will promote the mutual understanding of the various disciplines and reinforce the community ties, present a state-of-the-art overview of the field, and foster the rise of new ideas, networking and establishment of new collaborations.

We invite scientists with various background to attend this interdisciplinary event, and contribute to a blue-sky thinking about its future directions. The topics considered include, however are not restricted to:

• Magnetic nanowires, nanotubes, core-shell, three-dimensional scaffolds and nanostructures with curved geometries.
• Advanced synthesis methods, covering chemical, physical and nanofabrication methods.
• Dedicated characterization techniques, especially on single objects: low-noise, high-sensibility, revealing structural, magnetic, transport and other features with high resolution in space and/or time.
• Properties covering nanomagnetism, spintronic and multifunctional aspects
• Dedicated theory and simulations
• Existing and foreseen applications

The program consists of one full day of introductory lectures to provide a common understanding basis across all disciplines, followed by invited talks, contributed talks and poster sessions over two full days. Social events are also scheduled to promote networking. Invited speakers are mentioned below (provisional list).

The workshop will take place at the Fraunhofer conference center located in Waischenfeld, 40 km  North-East of Erlangen. A shuttle bus will be organized from and to Nürnberg and Erlangen railway stations, which themselves may be reached conveniently by long-distance train or from Nürnberg, Frankfurt and München airports. Arrival is scheduled on Monday 6^th evening, and the workshop will end on Friday 10^th, mid-day.

Financial support by the French-German ANR-DFG project Chemistry for 3D spintronics (C3DS) will allow us to offer attractive all-inclusive registration fees, covering access to the conference, social activities, board and accommodation, as well as the shuttle bus to the workshop venue. The participation of early-stage scientists will be encouraged.
