To build the ultrafast computers of the future, scientists are looking beyond the electrical charge of electrons to another property: their spin. While conventional hardware relies entirely on the movement of charge to process data, the ability to tap into this intrinsic quantum property could enable researchers to completely reinvent how information travels through a circuit./news/wp-json/wp/v2/posts/154951/n

Now, a team led by Â鶹ӳ»­´«Ã½ Professor of Physics Madhab Neupane has identified a promising candidate. Neupane and his collaborators found evidence of altermagnetism, an emerging form of magnetism that combines useful characteristics of the two more familiar types of magnetism: ferromagnetism and antiferromagnetism./news/wp-json/wp/v2/posts/154951/n

Ferromagnetism produces the behavior most people associate with everyday magnets. In these materials, magnetic moments align in the same direction, creating a magnetic field. That property can be useful in electronics, but the resulting stray magnetic fields can interfere with nearby components./news/wp-json/wp/v2/posts/154951/n

Antiferromagnets behave differently. Their magnetic moments point in opposing directions and cancel one another out, largely avoiding the stray fields. However, they lack some of the useful electronic properties found in ferromagnets./news/wp-json/wp/v2/posts/154951/n

Altermagnets offer another possibility by combining desirable characteristics of both./news/wp-json/wp/v2/posts/154951/n

Like antiferromagnets, they can avoid producing unwanted stray magnetic fields. But they can also generate and detect spin currents /news/wp-json/wp/v2/posts/154951/u2014 the movement of electron spins through a material /news/wp-json/wp/v2/posts/154951/u2014 that researchers hope to use for future electronics./news/wp-json/wp/v2/posts/154951/n
