Researchers create electrically tunable magnetism in a nonmagnetic 2D semiconductor
Scientists from the National University of Singapore and partners in Switzerland, the Czech Republic and Germany demonstrated electrically tunable magnetism in a two-dimensional semiconductor on October 12.
New method for magnetic control
The team introduced magnetism into an air-stable two-dimensional semiconductor material using electrical voltage. This process allows the magnetic properties of the substance to be switched or adjusted without physical changes to the structure. The study was led by assistant professor Ahmet Avsar with Qi Zhang as the first author.
Potential for spintronic devices
Conventional electronics rely on electron charge while spintronics utilizes electron spin for information processing. Combining these two functionalities could enable new approaches to memory and data storage technologies. The findings were published in the journal Science Advances as a significant step forward.
