Applying a magnetic field to a non-magnetic metal made it conduct 70% more electricity, even though basic physics principles would have predicted the opposite. Insights from pure mathematics are lending new insights to material physics, which could aid in development of new devices and sensors. “We never expected that magnetoresistance could be lowered even further in the compound we tested, because in theory it should have increased,” says Kyoto University study author Shingo Yonezawa.
Applying a magneticfield to metals affects how well they are able to conduct electricity...
