Unusual magnetic behavior observed at a material interface

August 18, 2015

Using neutron scattering methods, we were able to see proximity magnetism in real space - an important magnetism which could be used as low energy dissipation electronics.

The comments from Prof. Qi-Kun Xue from Tsinghua University:

The significance of this work is threefold,” says Qi-Kun Xue, a professor of physics at Tsinghua University in China who was not involved in this work. The three areas, he says, are “to demonstrate proximity magnetism, the enhancement of such magnetism … and the tunability of this interfacial magnetic structure.” He adds that the finding is a significant step toward a device application of magnetic topological insulators. “In particular,” he explains, “the consistent results from independent experimental tools” make the results “robust.
