Researchers demonstrate electrical creation and control of antiferromagnetic vortices
Researchers from the University of Nottingham, Diamond Light Source, Czech Academy of Sciences and The University of New South Wales have shown for the first time how electrical creation and control of magnetic vortices in an antiferromagnet can be achieved, a discovery that could increase the data storage capacity and speed of next generation devices.
The team used magnetic imaging techniques to map the structure of newly formed magnetic vortices and demonstrate their back-and-forth movement due to alternating electrical pulses.
