The main objective of this Priority Programme will be fundamental research on unconventional compensated magnets. This programme builds on the recent discovery of altermagnetism and the development of unconventional non-collinear antiferromagnets, which opened a first physical pathway to devices that combine both strong spin-polarised currents operating at THz time scales, with the highest possible data storage densities, overcoming the barriers faced by conventional ferromagnetism and antiferromagnetism.

Altermagnets are an emerging class of compensated collinear magnets with d/g/i-wave symmetry in both real space and the electronic band structure. In addition, the odd-parity-wave magnetic counterpart phases, i.e. p-wave, have also been recently recognised in non-collinear magnetic systems. These new unconventional magnets beyond s-wave order allow to expand the known ferromagnets and antiferromagnets paradigms. Their novel properties, the very large variety of material candidates reaching currently more than 400, and the many connections to other areas of condensed matter physics (topological quantum matter, spintronics, optics, neuromorphic computing, multiferroics, strongly correlated systems, twistronics, etc.), make this emergent field of unconventional magnetism a perfect platform for a Priotity Programme.

The Priority Programme will be structured in several subtopic research areas:

• Altermagnetic materials
• Noncollinear unconventional magnetic ordered systems
• Ultra-scalable hybrid systems and devices

A networking meeting (participation optional) with short presentations of the planned projects and subsequent discussions will take place on 2–3 September 2025 at the Johannes Gutenberg-Universität Mainz. Applicants who wish to participate in this network meeting are requested to send an e-mail to spp-unmag@uni-mainz.de by 14 July 2025 for organisational purposes.
