Creating an Electrical Switch for Magnetism
A team of researchers from the Dept. of Physics and the Dept. of Chemistry have worked together to discover magnetism of a magnetic semiconductor called Cr2Ge2Te6 that shows a great response to applied electric fields. The material was found to exhibit a state of ferromagnetism with temperatures up to 200k (-73 C). These results were fascinatingly surprising because it was unknown to have ferromagnetic order at these temperatures.

NUS physicists can show control of magnetism in a magnetic semiconductor through electrical use. This will continue to open the exploration for spintronic devices for future research with even more related materials systems.
