From the article
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 on the movement of charge to process data, tapping into this intrinsic quantum property could enable researchers to reinvent how information travels through a circuit.

University of Central Florida researcher discovers experimental evidence of new type of magnetism
Madhab Neupane’s UCF lab includes molecular beam epitaxy (MBE), angle-resolved photoemission spectroscopy (ARPES) and time-resolved ARPES systems. The Neupane group also conducts measurements at national synchrotron facilities. Measurements for this project were performed at the Advanced Light Source at Lawrence Berkeley National Laboratory and the Stanford Synchrotron Radiation Lightsource. Credit: Madhab Neupane
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 on the movement of charge to process data, tapping into this intrinsic quantum property could enable researchers to reinvent how information travels through a circuit.
Now, a team led by UCF physics professor 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 two more familiar types: ferromagnetism and antiferromagnetism. Their paper is published in the journal Nature Communications.
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.
Antiferromagnets behave differently. Their magnetic moments point in opposing directions and cancel one another out, largely avoiding stray fields. However, they lack some of the useful electronic properties found in ferromagnets.
