2020 Magnetism Roadmap with FELIX contribution
The Journal of Physics D – Applied Physics published the 2020 Magnetism Roadmap (open access). The article consists of 14 sections, each written by a leading expert in the field and addressing a specific subject, representing both the breadth of new research areas, and the desire to incorporate different voices and viewpoints. Andrei Kirilyuk wrote a section on all-optical magnetization reversal. As a collective effort of experts from 10 different countries, the 2020 Magnetism Roadmap is intended to provide a reference point and guide on relevant and emerging research directions in modern magnetism.
