Researchers report record-high magnetoresistance that appears in graphene under ambient conditions. In a paper published in Nature this week (13 Apr 2023), researchers from The University of Manchester report record-high magnetoresistance that appears in graphene under ambient conditions.
Materials that strongly change their resistivity under magnetic fields are highly sought for various applications and, for example, every car and every computer contain many tiny magnetic sensors. Such materials are rare, and most metals and semiconductors change their electrical resistivity only by a tiny fraction of a percent at room temperature and in practically viable magnetic fields (typically, by less than a millionth of 1 %)...
