A new way to control magnets
September 24, 2021
Researchers at MIT and elsewhere have developed a way of rapidly switching the magnetic polarity of a ferrimagnet 180 degrees, using just a small applied voltage. The discovery could usher in a new era of ferrimagnetic logic and data storage devices, the researchers say.
The findings appear in the journal Nature Nanotechnology, in a paper by postdoc Mantao Huang, MIT professor of materials science and technology Geoffrey Beach, and professor of nuclear science and technology Bilge Yildiz, along with 15 others at MIT and in Minnesota, Germany, Spain, and Korea.
