Among the chief complaints for smartphone, laptop and other battery-operated electronics users is that the battery life is too short and—in some cases—that the devices generate heat. Now, a group of physicists led by Deepak K. Singh, associate professor of physics and astronomy at the University of Missouri, has developed a device material that can address both issues. The team has applied for a patent for a magnetic material that employs a unique structure—a “honeycomb” lattice that exhibits distinctive electronic properties.
