Altermagnetism and beyond – a comprehensive article on new frontiers in magnetism published by a Czech-led team in Nature

The family of magnetic materials has been traditionally divided into the ferromagnetic branch known for several millennia and the antiferromagnetic branch known for nearly a century. Researchers from the Institute of Physics of the Czech Academy of Sciences, together with international collaborators, have recently made a discovery of a new branch of the magnetic family, termed altermagnetic. Now they publish an article in Nature which gives not only a comprehensive theoretical and experimental description of altermagnetism, but also shows how the discovery of altermagnetism inspires future research into an even broader landscape of unconventional magnets beyond the traditional ferromagnets and antiferromagnets.

The well known and broadly exploited ferromagnets offer a range of physical phenomena used, among others, for making memory bits on advanced-node integrated circuits. This so-called spintronic technology is the first in the history of IT to complement semiconductor bits on processor chips. However, using ferromagnets also imposes principal limitations on the spatial, temporal and energy scalability of the spintronic technology.
