A team of scientist from MIT, NIMS in Japan, Iowa State University and INL, have fabricated a new type of magnetic tunnel junctions where the tunnel barrier is made of a newly discovered two-dimensional magnet. This permits them to probe the magnetic properties of this new material and unveil unknown aspects of its magnetic behaviour. In addition, the devices present a very large magnetoresistance, the variation of electrical resistance upon application of magnetic fields, that forms the basis to many applications.
J. Fernández-Rossier, from INL, said that “these experiments, take advantage of electron tunnelling across these magnetic materials to explore magnons”.
These findings have been reported in the prestigious journal Science, edited by the American Association for the Advancement of Science, on May 3, 2018.
