Apr 13 2023Reviewed by Skyla Baily At the University of Manchester, scientists have reported record-high magnetoresistance that emerges in graphene under ambient conditions.Powerful materials that can alter their resistivity when subjected to magnetic fields are highly sought-after for various applications. For instance, magnetic sensors are used in every car and computer, making such materials indispensable.
Recently, a research group led by Professor Sir Andre Geim made an exceptional discovery: good old graphene, which has been studied extensively over the past 20 years, displays an incredibly strong response. It can reach over 100% in magnetic fields produced by standard permanent magnets . This is a record-breaking magnetoresistivity for any known material.
Over the last 10 years, electronic quality of graphene devices has improved dramatically, and everyone seems to focus on finding new phenomena at low, liquid-helium temperatures, ignoring what happens under ambient conditions.
