Researchers led by Professor Jung-Il Hong at DGIST's Department of Physics and Chemistry have shown that current pulses can rearrange the spin configuration inside a ferrimagnetic material. As a result, the material's compensation temperature—the point at which opposing magnetic ordering cancels—shifted downward.
The experiment is part of an effort to develop next-generation spintronic memory, which would store data using electron spin rather than charge. Being able to adjust the compensation temperature electrically, instead of through external heating or chemical tuning, could make such devices more practical.
This article is based on a single research report, so there are no conflicting findings to compare. The result is presented as a demonstration of a tunable effect rather than a finished device.
