Antiferromagnets do not have net magnetization. Future ultra-fast and energy efficient information storage, processing, and transmission platforms could be created by antiferromagnetic spintronic devices.
The devices need to be able to operate at room temperature in order to be useful. There is an injection of spin current at the antiferromagnetic interface. In the past, spin injection at these interface was done at a certain temperature.
In collaboration with researchers at the University of California, Irvine and the University of Utah, a team led by Barsukov has demonstrated efficient spin transport in an antiferromagnet. Spin transport is a key process in the operation of spin-based devices and the researchers observed that it is important in the antiferromagnet and ferromagnet.
The study appeared in the journal.
Barsukov is an assistant professor of physics and astronomy.
Barsukov was joined in the research by many other people.
